Temperature is a primary influencer of measurement uncertainty in strain gauge sensors. In this article, we look at how thermal specifications affect load cell accuracy and sensor selection.

To achieve high-precision results with load cells, test engineers must expand the review of basic temperature ranges and understand the mechanics of thermal compensation, the modulus of elasticity, and the resulting shifts in both zero and span.

Understanding compensated vs operating temperature range in load cells

Because strain gauges and metallic flexures are bonded to respond to thermal changes, manufacturers define performance boundaries in two distinct categories: the Compensated Temperature Range and the Operating Temperature Range.

The compensated temperature range is the specific thermal window where the sensor meets its stated accuracy specifications. When operating within this specification range, the thermal effect on zero and the thermal effect on output remain within the tolerances listed in the product’s data sheet. If the ambient temperature moves outside this range but stays within the operating range, the sensor will likely function, but the data is no longer guaranteed to meet the defined accuracy.

The operating range defines the absolute environmental limits that the sensor can withstand without suffering permanent damage or catastrophic failure. It accounts for the survival of internal components, such as adhesives, wiring insulation, and the strain gauge bond itself.

How temperature changes affect load cell accuracy and measurement stability

Every load cell flexure is subject to physical changes under temperature fluctuations. As the environment warms, the metallic alloy of the flexure undergoes a predictable change in its material properties, specifically its stiffness. This means that at higher temperatures, the same amount of force produces a slightly greater static deflection. Technically, this may cause the sensor to report a higher load than is present.

To ensure the highest accuracy, Interface manages these physical realities through two primary methods:

Proprietary strain gauges and thermal compensation techniques explained

The most effective way to handle thermal shift is at the source. Rather than adjusting the signal after it has been created, we use proprietary strain gauges specifically manufactured to match the thermal characteristics of the flexure material. By aligning the gauge’s performance with the metal’s expansion and contraction, we effectively cancel out the apparent strain through engineering design of the load cell. This ensures that the bridge circuit responds only to the mechanical load, not to the thermal environment, before the signal even leaves the sensor.

Why bridge excitation and sensor design matter in high-temperature testing

In addition to gauge selection when engineering a load cell, the internal bridge circuit is refined to maintain a consistent output. While some industry methods rely on external resistors, which can introduce lag in response time, a high-performance sensor integrates compensation directly into the bridge. This process stabilises the relationship between the excitation voltage and the signal output, ensuring that the sensitivity remains flat across the entire compensated temperature range. This level of precision allows the tight tolerances listed in the data sheet for both zero and span.

Defining the data boundaries

A high-level technical application requires moving beyond simple definitions to analyse how these specific thermal variables dictate data reliability during a live test.

To fully account for measurement uncertainty, load cell users need to distinguish between a shift in the baseline and a change in the sensor’s sensitivity when evaluating thermal accuracy.

The effect on zero, or the temperature coefficient of zero, represents the change in the no-load output due to thermal fluctuations. Physically, this manifests as a vertical shift in the calibration curve. If the ambient temperature remains stable throughout the test, this shift is repeatable and can be effectively neutralised by taring the instrument. The risk arises when the temperature fluctuates dynamically; in these scenarios, the zero shift becomes a moving target, introducing a baseline error that cannot be easily subtracted without synchronised temperature logging.

In contrast, the effect on output, known as the temperature coefficient of sensitivity, represents a change in the actual slope of the calibration curve. This is a significantly more complex error to manage because it is expressed as a percentage of the applied load rather than as a fixed offset. Unlike zero shift, this error cannot be tared out because the magnitude of the discrepancy scales with the measured force. As the applied load increases, the error in absolute units in pounds of force or Newtons expands proportionally. This makes it a critical factor in high-capacity testing, where even a small percentage shift in sensitivity can lead to substantial inaccuracies in data at the upper end of the measurement range.

Three critical thermal specification considerations for sensor selection

Thermal Gradient Management – A sensor is designed to be in thermal equilibrium. If one side of a load cell is near a heat source, such as a rocket manifold, and the other is near a heat sink, internal compensation cannot function correctly. This creates a non-linear thermal gradient error that does not appear on a standard datasheet.

Material selection – While aluminium offers high thermal diffusivity, allowing it to reach equilibrium faster, stainless steel or specialised alloys are often required in extreme environments to maintain structural integrity and fatigue rating at the upper limits of the operating range.

Repeatability and characterisation – Thermal shifts are often repeatable. In specialised testing projects using load cells where the environment cannot be controlled, engineers can characterise the sensor’s specific thermal profile and post-process the data to subtract the shift, provided the temperature was logged concurrently with the force data.

Thermal specifications – Selecting a sensor based solely on capacity ignores the realities of the test environment. For a test engineer, the compensated temperature range is the zone where accuracy is maintained by design. The operating temperature range is the boundary for hardware survival.

How thermal specifications affect long-term sensor reliability and fatigue rating

As an example, when selecting capacity for high-temperature applications, remember that the material’s fatigue rating may degrade as you approach the upper limits of the operating range. High heat can soften certain alloys, reducing the sensor’s long-term cycle life.

By understanding the interactions among the modulus of elasticity, proprietary strain gauge compensation, and thermal equilibrium, you move from simply collecting data to ensuring metrological traceability. Always calculate your potential thermal error at the expected temperature extremes before finalising your sensor selection. If you have additional questions about the thermal specifications and environmental considerations in selecting your load cell, contact our experienced application engineers.

FAQ – Frequently asked questions

What is a compensated temperature range in a load cell?

The compensated temperature range is the temperature window where a load cell or force sensor will meet its stated accuracy specifications. Within this range, thermal effects on zero and output remain within defined tolerances.

What is the operating temperature range of a sensor?

The operating temperature range defines the environmental temperature limits a sensor can physically withstand without permanent damage. Accuracy may not be guaranteed throughout the full operating range.

What is thermal compensation in force sensors?

Thermal compensation is the engineering process used to minimise measurement errors caused by temperature changes. It typically involves strain gage matching, bridge circuit refinement, and compensation techniques built into the sensor design.

What is the thermal effect on zero?

The thermal effect on zero, also called the temperature coefficient of zero, refers to changes in the sensor’s no-load output caused by temperature fluctuations.

What is the thermal effect on output?

The thermal effect on output, or temperature coefficient of sensitivity, describes how temperature changes alter the sensor’s measurement sensitivity and calibration slope.

Why do temperature changes affect load cell accuracy?

Temperature changes alter the physical properties of sensor materials, including stiffness and expansion characteristics. These changes can affect both the baseline output and measurement sensitivity of the load cell.

What is bridge excitation in a load cell?

Bridge excitation is the electrical voltage supplied to the Wheatstone bridge circuit inside a load cell. Stable excitation voltage helps maintain accurate and consistent sensor output.

Why is thermal equilibrium important in sensor applications?

Thermal equilibrium ensures the sensor experiences uniform temperature conditions. Uneven heating or cooling can create thermal gradients that introduce measurement errors not covered by standard calibration data.

How do material choices affect thermal performance in sensors?

Different materials respond differently to temperature changes. Aluminium may reach thermal equilibrium faster, while stainless steel and specialist alloys often provide better strength and fatigue resistance in extreme environments.

What is a fatigue-rated load cell?

A fatigue-rated load cell is specifically designed to withstand high-cycle loading applications without performance drift or structural degradation over time.

What are ultra miniature load cells?

One of the challenges product and test engineers face is integrating high-performance force measurement into constrained physical envelopes. In response, Interface offers a range of options we classify as ultra miniature load cells, with dimensions from less than 0.5 inches to under 2 inches in height or width.

Why compact force sensors matter in modern product design

Interface Ultra Mini Load Cells maintain the demanding performance standards of larger models while addressing the spatial limitations inherent in testing small components or integrating them into devices, parts, or end-products.

Types of ultra miniature load cells and their applications

Selecting an ultra miniature sensor requires understanding the specific form factor and how it handles external loads. The core of this category includes using load cells that fit dimensionally and by capacity and capabilities. Here are a few of Interface’s models designed for these requirements.

• ULC Ultra Low Capacity Load Cell is engineered for light force measurement, where sensor mass could interfere with test results.
• SuperSC S-Type Miniature Load Cell and SMA Miniature S-Type Load Cell models take advantage of the standard S-Type geometries scaled down for tension and compression in tight vertical spaces.
• MBS Parallelogram Load Cells utilise a beam design to provide high accuracy in low-capacity scales and weighing equipment.
• WMC Sealed Stainless Steel Miniature Load Cells are a very popular option for their industrial design and performance, making them a good choice for environments where moisture or debris are factors.
• MTFS Miniature Tension Force Load Cell and SMTM Micro S-Type Load Cell are specialised micro-designs for tension-only or micro-scale force monitoring.
• MCC Miniature Compression Load Cell is a miniature compression-only cell for high-capacity applications.

Comparing ULC and SuperSC ultra mini load cells

Within the ultra mini grouping, the ULC and the SuperSC represent different engineering philosophies for small-envelope force measurement. While both occupy a footprint under 2 inches, they are optimised for opposite ends of the force spectrum.

Micro-force precision vs high-capacity measurement

The ULC is engineered for micro-force precision, measuring forces as low as 0.1 Newton. Its internal parallelogram structure is designed to be highly sensitive while remaining robust enough to handle accidental sideloading. This design ensures that the load remains centred and minimises the impact of off-centre placement, which is common when working with microscopic components or delicate filaments.

Using miniature S-Type load cells in tight spaces

In contrast, the SuperSC is designed for high-density force. It allows an engineer to measure up to 1,000 lbf in a package roughly the height of a matchbox and the diameter of a quarter coin. Its S-type form factor geometry makes it much easier to integrate into tension links or threaded assemblies using rod-end bearings.

While the ULC is often used in stationary benchtop micro-testing, the SuperSC is frequently found in in-line industrial applications or integration into equipment such as a 4D Bio Printing machine.

The primary distinction for selection is resolution versus capacity. The ULC is used when the priority is detecting sub-gram changes in force, where extraneous cable weight could be a factor. SuperSC is the choice when high-capacity tension and compression data are required within a confined mechanical linkage.

Best practices for ultra miniature load cell installation

Using ultra miniature sensors reduces the overall weight of the test assembly. This is critical in dynamic applications where the sensor mass affects the system’s frequency response or natural resonance.

Tip #1: Improving signal-to-noise ratio in low-capacity load cells

Because these sensors often operate at lower capacities, the output signal in millivolts is small. Users must prioritise high-quality shielded cabling and keep cable runs as short as possible to prevent electromagnetic interference from degrading the data. In many ultra-miniature load cell model designs, the cable diameter itself can exert a parasitic force on the sensor if not properly routed or free of strain.

Tip #2: Mounting and alignment tips for mini load cells

The reduced surface area of ultra miniature load cells makes them more sensitive to off-centre loading and side loads. For S-Type models SMA, the use of rod-end bearings is recommended to ensure the load remains axial. For compression-only models like the MCC, the loading surface must be flat and parallel to avoid introducing bending moments that skew accuracy. The SuperSC is designed to reduce off-centre loading.

Tip #3: Thermal management considerations for compact sensors

Smaller sensor bodies have less thermal mass, meaning they react more quickly to ambient temperature shifts. While these cells include internal temperature compensation, sudden thermal gradients can cause a zero shift. Engineers should consider the proximity of the sensor to heat-generating components like motors or processors in compact housings.

Ultimately, the successful use of these ultra load cells relies on acknowledging the physical sensitivity of the small form factor while leveraging its ability to provide data at the primary point of force contact.

Interface Ultra Mini Load Cell Application Examples

Medical, robotics and electronics applications for ultra mini load cells

In robotic-assisted surgery, miniature sensors like the MCC or SMTM are integrated into the distal ends of surgical instruments. These sensors provide real-time force feedback, known as medical hapticals, to the operator, allowing for precise tissue manipulation and suturing without the risk of over-tensioning delicate materials.

Food quality

Agriculture, food storage, and produce quality control require a reliable and quantifiable method to assess the ripeness of fruits and vegetables. Interface suggested implementing the WMC Stainless Steel Miniature Load Cell, which was integrated into a penetrometer device equipped with a penetrating tip, as noted in our harvest penetrometer app note.

Medical devices and research

The MBS Parallelogram Load Cell is often embedded within medical infusion devices to monitor fluid weight or detect occlusions in the tubing. The compact beam design allows for integration into portable, battery-operated units where every millimetre of space is allocated to electronics or fluid reservoirs. A requirement for DNA replication, or DNA synthesis, is the process of a cell making an identical copy of its DNA.  Interface’s SMTM Micro S-Type Load Cells are placed in the column where fluids from the synthesiser are dispensed.

Electronics testing and assembly

In automated assembly, the MTFS can monitor the force applied during the pick-and-place process. This prevents fragile components from being crushed while ensuring that electrical connections are fully seated under the correct amount of pressure. Interface’s SMTM Micro S-Type Load Cell is ideal for touchscreen testing. The SMTM can be easily integrated into a force testing machine. The touchscreen is laid flat under the machine, and force tests are conducted in different locations of the touchscreen.

Force measurement in drone and UAV testing

Miniature S-Type sensors, such as the SuperSC, are used in small-scale propulsion labs to measure the thrust and torque of micro-drones. The high accuracy-to-size ratio allows researchers to build compact test stands that can be used in wind tunnels without significantly disrupting the airflow.

Challenges of integrating ultra miniature force sensors

The integration of Ultra Mini Load Cells requires a disciplined approach to mechanical coupling and signal conditioning. Because these sensors are often deployed in systems where the margin for error is measured in microns or grams, the boundary between the sensor and the application must be rigid and perfectly aligned. Any parasitic friction or unintended mechanical shunts will disproportionately affect the accuracy of a miniature cell compared with that of its larger counterparts.

High-speed data acquisition for compact load cells

From a data acquisition perspective, the high natural frequency of these compact sensors makes them excellent candidates for high-speed sampling. However, to fully realise the precision of these very small sensors, including our ULC or SuperSC series, instrumentation must be capable of resolving low-level signals in high-vibration or electrically noisy environments. Utilising instrumentation with high input impedance and dedicated excitation regulation is essential to maintain the stability of the bridge circuit over long-term testing cycles.

Ultimately, classifying a load cell as ultra mini reflects its volumetric efficiency. Whether the application requires the delicate micro-force resolution of a parallelogram beam or the high-capacity tension capabilities of an S-Type, these sensors provide the necessary bridge between extreme spatial constraints and laboratory-grade measurement certainty.

Frequently asked questions about ultra miniature load cells

Esports’ shift from casual play to precision hardware

The shift from casual gaming to professional esports has fundamentally changed the hardware’s mechanical requirements. In a recreational setting, a controller or keyboard is just a basic input device. In esports, however, it becomes a precision tool where consistency and accuracy can decide the outcome of multi-million-dollar tournaments.

The rise of esports has driven a change in testing standards, moving from simple functional checks to detailed mechanical analysis using sensor technologies. For today’s esports athletes, equipment must not only be dependable but also deliver a perfectly repeatable tactile response.

The demands of esports on tournament infrastructure have also increased, leading to specialised testing of arena-scale setups to ensure that the same high level of precision found in handheld controllers is maintained in large, high-stakes environments.

From functional inputs to force-based evaluation

One of the biggest advances in gaming is shifting from displacement-based inputs to force-based systems. In traditional hardware, a controller or pedal might only detect how far a component moves. But in professional simulation, this doesn’t capture the subtlety needed for top performance, where muscle memory is linked to tension rather than distance.

Measuring force in simulation: racing and braking controls

A perfect example is the use of the Interface BPL Pedal Load Cell in racing simulators. Engineers can measure the actual braking force a driver applies. This enables the software to replicate the hydraulic physics of a real vehicle, with the engagement point determined by force. With a nonlinearity of less than 0.05%, these sensors provide the precise, high-quality data necessary for trail braking, where a driver must carefully reduce pressure to keep traction through a turn.

Video: Gaming simulation brake pedal

A gaming company wants to switch from the standard racing pedals, to a load cell based pedal system for their racing simulation game. Compared to the standard racing simulation pedals, load cell pedals are more advanced and offer more accurate results. They want a wireless system that will measure the strength of the pressure received by the pedals that will detect the perfect amount of braking power. Watch the video to find out more.

Video – Gaming simulation brake pedal

Tactile consistency: keyboards, mice and peripherals

For peripherals like keyboards and mice, the design and test engineering focus is on tactile consistency. A professional gamer often executes hundreds of actions per minute, making the actuation profile of each key critical.

Using miniature load cells, manufacturers precisely map the force-displacement curve of mechanical switches. This process determines the exact force needed to trigger a command versus the force required to bottom out the key. For example, by maintaining consistency across all keys, manufacturers ensure that player performance isn’t disrupted by a heavy or inconsistent switch.

The same level of scrutiny is applied to console triggers and mouse touchpads, where load cells monitor durability to keep click tension consistent from the first day of use to the last.

Immersive haptics and virtual reality force analytics

As virtual reality and haptic technology evolve, force measurement helps bridge the gap between digital and physical experiences. Micro Load Cells, like our SuperSC and ULC, are embedded in haptic gloves and suits to adjust the tension of internal actuators. This guarantees that when a user interacts with a virtual object, the resistance they feel accurately corresponds to the object’s density and weight.

Additionally, these sensors are extending beyond hardware into player analytics. Coaches now use load cells to measure the rate of force development. This metric indicates how quickly an athlete can reach the necessary actuation force for a button press, effectively assessing physical lag. This data-driven approach enables teams to improve player technique and detect fatigue before it affects game performance.

Technical applications in simulation and infrastructure

While the focus often falls on the player’s experience, force measurement is just as crucial for the environment and secondary controls. In simulation, multi-axis sensors ensure that yokes and joysticks deliver the right resistance across three dimensions.

Structural force monitoring for esports venues

In the physical space, the measurement scale shifts to structural safety. Tension link load cells and wireless shackles are vital for real-time monitoring of the massive overhead displays and rigging that define modern esports venues.

Using our LW General Purpose Load Washer Load Cell and Interface WTS system, engineers remotely monitor these structural loads for large display screen mounts, ensuring the thousands of pounds of equipment suspended above the stage stay balanced and secure during a live event.

The growing esports market and engineering impacts

As of 2026, the global esports market has exceeded $5 billion in valuation, with a dedicated audience of over 335 million fans. This growth has transformed gaming hardware into a specialised industrial sector where sustainability, AI-driven performance analysis, and zero-latency wireless connectivity are now the standard. Manufacturers are no longer simply making toys; they are designing high-performance tools that must meet the same safety and precision standards as aerospace or automotive parts.

Load cells are at the heart of modern force and weight measurement systems—but what’s actually inside them?

In this training video, we break down the internal structure of a load cell and explain how each component contributes to accurate, reliable measurement. Whether you’re new to force measurement or looking to strengthen your foundational knowledge, understanding load cell anatomy is essential.

What is a load cell?

A load cell is an electro-mechanical sensor that converts force into an electrical signal.

When force or weight is applied, the sensor experiences a very small deformation. This deformation is then translated into a measurable electrical output, allowing precise force or weight readings.

The two main parts of a load cell

At a high level, most load cells consist of two key elements:

1. The load-bearing structure (spring element)

This is the physical body of the load cell—typically made from high-strength steel or aluminium.

• Designed to deform slightly under load
• Engineered for predictable, repeatable strain
• Maintains structural integrity even under repeated use

This controlled deformation is critical. Without it, there would be no measurable change to detect.

2. The electrical measurement system

Inside the load cell is a circuit that detects and converts mechanical strain into an electrical signal.

This includes:

• Strain gauges
• Wiring and connections
• Signal output components

Together, these elements transform physical force into usable data.

Strain gauges: The heart of the measurement

Strain gauges are the most important sensing component inside a load cell.

• Made from very thin conductive foil or wire
• Arranged in a zig-zag pattern for sensitivity
• Bonded directly to the load cell structure

When the load cell deforms, the strain gauges stretch or compress. This changes their electrical resistance in direct proportion to the applied force.

The Wheatstone Bridge Circuit

To measure these tiny resistance changes accurately, strain gauges are typically arranged in a Wheatstone bridge configuration.

This setup:

• Combines multiple strain gauges into a balanced circuit
• Amplifies small resistance changes
• Improves measurement sensitivity and accuracy

The result is a stable, precise electrical signal that reflects the applied load.

How a load cell measures force (step-by-step)

Here’s how all the internal components work together:

1. Force is applied to the load cell
2. The metal structure deforms slightly
3. Strain gauges detect the deformation
4. Their electrical resistance changes
5. The Wheatstone bridge converts this into a signal
6. Electronics amplify and output the measurement

This process happens almost instantly and with extremely high precision.

Additional internal features

Beyond the core components, load cells often include:

Protective materials (potting or sealing)

Internal components are typically sealed with epoxy or similar materials to:

• Protect against moisture and contaminants
• Improve durability in harsh environments

Cable and output connections

These transmit the electrical signal to:

• Indicators
• Data acquisition systems
• Control systems

Mechanical design features

Including:

• Defined load paths
• “Dead end” and “live end” mounting points
• Geometry optimised for specific force types (tension, compression, shear)

Why understanding load cell anatomy matters

A clear understanding of what’s inside a load cell helps you:

• Select the right sensor for your application
• Install and mount it correctly
• Troubleshoot measurement issues
• Maximise accuracy and reliability

Even small errors in alignment or installation can affect performance, as load cells rely on a precise load path and controlled deformation.

Common applications of load cells

Load cells are used across a wide range of industries, including:

• Industrial weighing systems
• Aerospace testing and validation
• Automotive component testing
• Medical devices
• Manufacturing process control

Their versatility comes from their ability to deliver consistent, high-accuracy measurements across many environments.

What’s inside a load cell – final thoughts

While a load cell may appear simple from the outside, its internal design is a carefully engineered system that combines mechanical precision with electrical sensitivity.

From the load-bearing structure to the strain gauges and circuitry, every component plays a vital role in delivering accurate force measurement.

If you’re working with load cells—or considering integrating them into your application—understanding what’s inside is the first step toward getting the most from your measurement system.

❓ Frequently Asked Questions About Load Cells

What is a load cell and how does it work?

A load cell is a sensor that converts force or weight into an electrical signal. It works by measuring the small deformation that occurs when a load is applied to a metal structure. This deformation is detected by strain gauges, which change electrical resistance in proportion to the force.

What are the main components inside a load cell?

Most load cells consist of a load-bearing structure (spring element), strain gauges, and an electrical circuit—typically a Wheatstone bridge. Additional components may include protective sealing, wiring, and output connections.

What is a strain gauge in a load cell?

A strain gauge is a thin conductive element bonded to the surface of the load cell. When the load cell deforms under force, the strain gauge stretches or compresses, causing a change in its electrical resistance that can be measured.

What is a Wheatstone bridge and why is it used in load cells?

A Wheatstone bridge is an electrical circuit used to measure very small changes in resistance. In load cells, it combines multiple strain gauges to improve sensitivity, accuracy, and stability of the output signal.

How accurate are load cells?

Load cell accuracy depends on factors such as design, calibration, and installation. High-quality load cells can achieve very high levels of precision, often within a fraction of a percent of the full-scale output when properly installed and maintained.

What is force intelligence in heavy machinery?

Manufacturers and engineers who design and test heavy machinery are making a sweeping transition from basic mechanical structures to intelligent systems, as mandated by modern requirements across various industries.

Extracting high-fidelity force data from high-capacity equipment

The primary challenge in modernising any equipment is extracting high-fidelity data from high-capacity environments without compromising structural integrity. Shifting from external monitoring to integrated force measurement addresses these technical hurdles at the design and production levels.

Load cells and torque sensors for heavy machinery testing and optimisation

Our solutions are transforming the design, testing, and operation of heavy machinery assets across diverse global industries. From massive earthmoving equipment to high-precision agricultural machines, our range of load cells, torque transducers, and wireless telemetry systems provides accurate measurement data required to optimise performance and safety.

Integrating force sensors directly into the mechanical load path

By integrating these sensor technologies directly into the mechanical load path, heavy machinery manufacturers are moving beyond basic monitoring and into the era of force intelligence. Whether used for real-time control via a PLC or for standalone safety monitoring in the field, our products provide the foundational force, torque, and weight data that help prevent failure and extend equipment life.

Structural integration of sensor-enabled components in heavy equipment

A significant hurdle for heavy machinery OEMs is the trade-off between adding sensors and preserving the machine’s original mechanical geometry. In such cases, our load pins and load shackles are finding a functional purpose as active structural components.

By replacing a standard pivot pin or clevis with a sensor-integrated version, you capture data directly in the load path. This eliminates the need for external mounting kits that introduce parasitic loads and mechanical lag. The result is a streamlined design where the sensor serves as the primary structural joint.

Maintaining signal integrity in high-torque industrial environments

Testing engineers require sensor immunity to harsh operating conditions. Heavy machinery often operates in environments involving significant electromagnetic interference from high-powered motors, vibration-induced signal jitters, and thermal drift from hydraulic systems.

Our sensors use strain gauge technology with high signal-to-noise ratios. When paired with our robust wireless telemetry products, these systems can eliminate the cabling requirements typical of traditional test stands. This leads to faster test setups and cleaner data for analysing the dynamic stress profiles of prototypes.

Real-time force monitoring through PLC integration

Integrating our sensors into a programmable logic controller (PLC) system moves force data from a static measurement to a live control variable. Using Interface digital instrumentation, such as DMA2 DIN rail-mount signal conditioners or the INF-USB3 PC Interface Module, engineers can feed high-resolution force and torque data directly into the machine control architecture via protocols such as CAN bus, Ethernet/IP, or IO-Link.

Enabling autonomous machine control with force intelligence

This integration allows the machine to make autonomous decisions based on physical stress. The following applications demonstrate how our products enable this shift across various heavy machinery designs.

#1 Autonomous grade control in earth moving machinery

In standard excavation, a machine follows a programmed GPS path but cannot sense varying soil density or hidden obstructions. By integrating our load pins, such as our ILMP Standard Stainless Steel Load Pin, into the bucket linkage and feeding that data to the PLC, the machine gains a tactile sense of the material it is moving. Our load pins replace standard pivot pins to measure the actual resistance encountered by the bucket. When the PLC detects a force spike through a DMA2 signal conditioner that exceeds efficient operating ranges, it automatically adjusts the blade angle or bucket curl. This prevents hydraulic overheating and structural fatigue while ensuring the autonomous system maintains a consistent grade without manual operator intervention.

#2 Sensor-based payload monitoring for forestry and waste management

In forestry and waste management, our sensors provide critical standalone data for field operations that are reliant on heavy machinery. Our wireless load shackles and tension links allow operators to monitor cable tension on log skidders and harvesters directly through a handheld WTS display. This ensures log loads remain within safe hauling limits without the need for complex vehicle integration. Our load pins embedded in waste management equipment hydraulic lift arms to provide real-time weight data to an in-cab display, allowing operators to verify payloads and avoid road-overload fines and equipment damage.

#3 Precision draft control and yield tracking in smart farming equipment

Interface force measurement products are used in smart farming to provide immediate feedback on field conditions. In agriculture, Our load pins are integrated into tractor three-point hitches for draft control. Rather than relying on a control network, these sensors can provide direct analogue feedback to hydraulic valves, automatically adjusting the ploughing depth based on soil resistance. Additionally, SSB Sealed Beam load cells are mounted on heavy equipment used for transportation and weighing to provide accurate measurements in outdoor environments, ensuring precise data for yield tracking and animal health.

#4 Active stability and tip-over prevention in mobile cranes

Heavy machinery, such as mobile cranes, often relies on static load charts that do not account for dynamic variables like wind gusts or sudden shifts in the centre of gravity. Integrating our load cells or tension links directly into the outriggers and hoist lines creates a live safety loop. The PLC continuously compares the reactive forces at each outrigger using our low-profile load cells. If the instrumentation detects a corner approaching a zero-load state, the PLC triggers a soft-stop or restricts boom extension. This type of use case transforms the crane from a passive lifting tool into an active safety system that corrects for environmental variables that human operators or simple limit switches might miss.

#5 Predictive drill-head optimisation for mining operations

Drilling through non-homogeneous rock creates unpredictable torque profiles that can damage drivetrains or snap drill bits. Placing an Interface rotary torque transducer in the drill string and connecting it to the PLC allows engineers to monitor the exact mechanical bite of the drill. Using an Interface T2 or T25 series rotary torque transducer, the PLC monitors the torque-to-penetration ratio. If the sensor detects high-frequency vibrations or torque patterns associated with specific rock hardness, the PLC automatically modulates rotational speed and downward pressure. This closed-loop control maximises consumable lifespan and prevents the catastrophic downtime associated with retrieving a broken drill string from a deep bore.

Using multi-axis sensors for accurate structural modelling

In production engineering, the accuracy of a digital model depends on the physical data used for calibration. Multi-axis sensors that measure force and moment across three axes simultaneously allow testing engineers to capture complex real-world stresses that single-axis cells miss. This high-fidelity data supports more precise light weighting during the design phase. When the exact forces applied during a duty cycle are known, engineers can reduce material overhead without sacrificing structural reliability.

Modern heavy machinery for construction, mining, and agricultural are using force intelligence. Our sensors enable the transformation of standard mechanical joints into smart components that provide the data-driven insights necessary for modern, high-production operations.

Integrating these solutions into the design and testing phases of heavy machinery ensures that every component is monitored for performance and fatigue. By making our force measurement a foundational part of the bill of materials, engineering teams can validate machine safety and performance with higher certainty.

Why overlooked measurement chain variables can derail sensor ROI

In the pressure world of industrial R&D, the difference between a successful product launch and a multi-million-dollar project delay often hinges on a single, overlooked variable in the measurement chain. When considering the requirements for a high-accuracy sensor, a single error in the output instrumentation or a misunderstanding of the wiring setup can derail an entire project.

Why force measurement sensors are not commodity components

Today, catalogue-driven procurement is common for standard components, and availability is often mistaken for optimisation. However, a force measurement sensor is not just a modular commodity. It is a sophisticated instrument that is only as effective as the system it operates within.

How system-level thinking protects data integrity in force measurement

To close the gap between lab-grade specifications and real-world reliability, buyers must look beyond the primary data sheet to uncover the hidden technical challenges that could threaten data integrity. The following considerations are critical when evaluating your use case, requirements, and connections in securing the measurement chain for accurate, data-driven success. Consider these in your ROI optimisation strategy.

Why mounting surface design is critical for load cell accuracy

The mounting environment is often the silent killer of ROI in test and measurement. During the mechanical fit phase, engineers sometimes treat the base or framework as passive support, which is a structural liability. For high-precision hardware such as the LowProfile™ Load Cell Series, the rigidity and flatness of the mounting surface are just as critical to measurement accuracy as the internal strain gages themselves. For example, will you use a pancake load cell with an installed base?  These are the dimensional considerations that can derail sensor ROI. No matter the sensor type, mini beams or multi-axis, it is important to determine your mounting surface requirements upfront.

When a mounting surface deflects or is not perfectly flat, it causes off-axis loading errors. This not only skews the data but also triggers a troubleshooting cascade that can delay testing by weeks. Beyond flatness, thread and bolt pattern matching must be precise to avoid parasitic torques.

⇒ Key Takeaway: The goal of surface preparation is to prevent off-axis loading errors. Ignoring these mechanical details is the most common cause of avoidable system-level inaccuracies.

Preventing signal degradation: cable selection and sensor interconnect design

Once the physical foundation is in place, the next challenge is the data’s path. The interconnect is often seen as simple cabling, but it can act as an antenna for electromagnetic interference, causing voltage degradation.

Choosing between a 4-wire and 6-wire configuration is a crucial decision for maintaining signal integrity. While 4-wire setups may be sufficient for short distances, they become inadequate for longer runs, where cable resistance causes significant voltage drops.

⇒ Tip: Using a 6-wire cable for long distances allows remote sensing, which compensates for and corrects voltage-drop errors, ensuring the excitation voltage at the sensor stays steady.

Why sensor datasheets alone cannot guarantee measurement accuracy

One common misconception in engineering is that a sensor’s data sheet guarantees application accuracy straight out of the box. A data sheet shows ideal conditions in a lab, but your application reflects real-world system behaviour.

True system-level calibration requires pairing the sensor with the instrument and calibrating them together. This process accounts for the unique scaling factors and electrical quirks of your specific setup. For those managing large fleets of hardware, including a Transducer Electronic Data Sheet (TEDS), is crucial. TEDS enables plug-and-play operation, in which the instrument automatically recognises the sensor’s specific sensitivity. Without this pair calibration, the accumulated errors between the sensor and the indicator can cause a high-accuracy system to perform poorly.

Designing sensors for dynamic loads, fatigue, and real-world conditions

Choosing a sensor based solely on its rated capacity is a recipe for failure. Expert-level selection involves designing for unexpected dynamic spikes and high-cycle fatigue that occur in real-world environments.

There is a critical difference between a functional sensor and an accurate one. If a dynamic spike exceeds the safe overload percentage, the sensor’s internal characterisation can be permanently damaged. It may still send a signal, but that signal becomes unreliable. For high-cycle environments, fatigue-rated sensors can withstand millions of cycles without drifting.

⇒ Key Takeaway: Matching the hardware’s IP rating to specific environmental hazards is essential to prevent environmental fatigue from increasing your Total Cost of Ownership.

Digital integration and cybersecurity in modern sensor systems

The final stage of optimisation is the digital handshake. As industrial environments shift toward Industry 4.0 and 5.0, the final data destination determines the hardware selection. If your architecture depends on a PLC, the raw signal must be converted to specific analogue outputs or digital protocols such as EtherCAT, Profibus, or Ethernet/IP.

However, the modern digital handshake now includes data management and cybersecurity. You need to consider how data is timestamped, synchronised across multi-axis matrices, and protected against unauthorised access. Traceability, which ensures every data point can be traced back to a specific calibration event, is no longer optional. It is a requirement for modern quality standards.

Planning the measurement system early to maximise sensor ROI

The Interface Sensor Selection Guide was created specifically to help you navigate these critical variables. It serves as an essential framework to prompt these reminders at every stage of your project, ensuring you see beyond the datasheet to the system-level reality.

Choosing the right measurement system means managing hundreds of variables that a simple spreadsheet cannot include. The most successful projects involve early contact with Interface’s Representatives, Distributors, and Application Engineers, who can assist you in avoiding pitfalls in sensor selection and in meeting your exact needs.

Frequently asked questions

What does sensor ROI mean in force measurement systems?

Sensor ROI refers to the value gained from a sensor investment through improved measurement accuracy, reliable data acquisition, reduced testing delays, and optimised system performance. Achieving ROI requires careful integration of sensors, instrumentation, mounting structures, and data systems.

What are the most common mistakes that reduce sensor ROI?

Common oversights include poor mounting surface preparation, signal loss from incorrect wiring, relying solely on datasheet specifications, ignoring dynamic load conditions, and failing to calibrate sensors at the system level.

Why is mounting surface design important for load cells?

The mounting surface directly affects measurement accuracy. If the surface is not rigid, flat, or properly aligned, it can introduce off-axis loading and structural deflection that distort measurement results and reduce system reliability.

How can wiring and interconnect design affect sensor performance?

Improper wiring or cable selection can introduce voltage drop, electromagnetic interference, and signal degradation. For longer cable runs, configurations such as six-wire sensing can help maintain signal integrity and accurate excitation voltage.

Why isn’t a sensor datasheet enough to guarantee accuracy?

Datasheets describe sensor performance under ideal laboratory conditions. Real-world applications involve additional variables such as instrumentation compatibility, wiring resistance, and environmental factors, which must be addressed through system-level calibration.

How can engineers maximise ROI from force measurement sensors?

Engineers can improve ROI by considering the entire measurement chain early in the design process, selecting sensors appropriate for dynamic loads and fatigue cycles, ensuring proper mounting and wiring, and implementing system-level calibration and data management practices.

What Is a thrust stand? — aerospace test rig explained

Thrust is the mechanical force generated by an engine or propulsion system to move a vehicle through the air or space. It is a direct application of Newton’s Third Law of Motion: for every action, there is an equal and opposite reaction. In aerospace, measuring this reaction accurately is the difference between a successful orbit and a structural failure.

In the aerospace industry, where there is zero room for error, accurately measuring a propulsion system’s reaction is critical to ensuring mission success and structural safety.

How thrust stands measure propulsion force – load cells and capture data

A thrust stand is a specialised test rig designed to hold a propulsion system such as a jet engine, rocket motor, or drone propeller, in a fixed position while it is fired. The stand must be rigid enough to contain the engine’s power, while allowing the force produced to be transferred to a measurement device.

As detailed in this Jet Engine Thrust Test App Note, the Interface provided sensors to conduct a static jet engine thrust test that accurately determines the engine’s thrust, burn time, chamber pressure, and other parameters, providing invaluable data to propellant chemists and engineers. They need a high-accuracy load cell with excellent repeatability to withstand thrust forces in very harsh environments. Here is how it works:

• The 1000 High-Capacity Fatigue-Rated LowProfile™ Load Cell is installed into the static test stand.
• The jet engine is ignited and produces full thrust.
• The load cell absorbs the thrust force and outputs a signal directly to the 9330 High-Speed Data Logger.
• Data is measured and recorded on the customer’s laptop using the included BlueDAQ software.

A thrust stand serves as a specialised laboratory for propulsion systems. Whether testing a UAV electric motor or a heavy-lift rocket engine, the stand must remain rigid enough to contain massive energy while being sensitive enough to transfer that force directly to a measurement device. Interface load cells act as the high-precision bridge in this setup, converting raw physical power into actionable engineering data.

Interface sensors in aerospace — precision load cells & custom solutions

Interface specialises in force measurement solutions that offer the accuracy and reliability required for highly regulated aerospace environments. Interface is a leading supplier of load cells for aerospace thrust and structural tests, due to our sensor designs, capacities, engineered-to-order specifications, performance, and customisation. Here are a few examples:

• Integration of load cells into thrust stands by mounting fatigue-rated LowProfile load cells, such as the 2000 High-Capacity Series or Fatigue-Rated LowProfiles, directly into the test rig captures the engine’s axial force. Interface load cells capture the engine’s axial force for analysis and verification.
• Customisation of sensors for the scale of massive structures like NASA’s Space Launch System (SLS) is common. Interface uses Finite Element Analysis (FEA) to customise proven high-capacity load cell designs, delivering custom sensors that measure loads with 0.05% accuracy.
• Dynamic response in propulsion testing involves rapid force transients. Interface sensors provide the high-frequency response necessary to capture data from initial ignition through to shutdown.

Thrust testing vs structural testing — key differences for engineers

While both rely on high-capacity and durable load cells, they differ in their fundamental mission. Structural testing focuses on the vehicle’s body, while thrust testing is about its power.

Structural testing rigs

These rigs are designed to verify airframe integrity and fatigue life. The objective is to ensure the fuselage, wings, or landing gear do not break or permanently deform under pressure. These setups typically involve distributed, multi-point loads where hydraulic actuators “push and pull” the vehicle to simulate the complex stresses of flight. Read more in Structural Testing with Interface Force Measurement Solutions.

Thrust testing rigs

These rigs are built to measure propulsion output and efficiency. The goal is to map the “thrust curve” and verify engine specifications against design requirements. Unlike the distributed loads encountered in structural testing, a thrust rig handles a concentrated axial force. The engine is bolted to a fixed stand, and its raw power is applied directly to the sensors to quantify performance. Read more in The Criticality of Thrust Measurement Testing in Aerospace

Aerospace thrust applications — from rockets to UAV propulsion

• Rocket Engine and Heavy-Lift Validation – In deep-space exploration programs, massive Interface custom load cells are integrated into test stands to measure the immense thrust of rocket motors. By attaching sensors to hydraulic cylinders at strategic points, engineers can verify how the fuselage responds to the intense loads experienced during a launch sequence.
• Jet Engine Performance Mapping – For aviation manufacturers, Interface fatigue-rated sensors are the standard for jet engine thrust stands. These sensors allow engineers to map performance from idle to maximum output, withstanding the repetitive, high-vibration environments typical of jet propulsion R&D. Review the Jet Engine Thrust Test application.
• UAV and eVTOL Characterisation – In the field of electric flight, Interface miniature load cells and torque transducers measure propeller and rotor thrust. This precision is vital for optimising battery efficiency and ensuring stable lift-to-weight ratios for autonomous systems.
• Wind Tunnel Vector Analysis – Thrust is rarely perfectly linear. In wind tunnel environments, Interface multi-axis sensors characterise complex force vectors, allowing aerodynamicists to understand how an engine’s output affects aircraft balance and stability.
• Space Simulation and Vacuum Testing – Satellite propulsion must be tested in conditions that mimic the vacuum of space. Interface provides vacuum-rated load cells that operate without outgassing, ensuring accurate measurement of even low-level thrust in simulated orbital environments.

Global demands in aerospace — commercial space & future innovations

We are currently in a transformative era of aerospace expansion. The “Race to Space” is no longer just a competition between nations; it is a $1.8 trillion commercial frontier. This burst in activity has created an unprecedented global demand for high-fidelity thrust testing rigs.

The commercialisation of global broadband is driving manufacturers to test thousands of small thrusters at an accelerated pace. Simultaneously, the reusable rocket revolution has shifted requirements. Engines must now be rated for multiple firings, necessitating fatigue-intensive testing to certify them for repeated flights.

Furthermore, as ambitions for the Moon and Mars grow, the scale of propulsion is reaching new heights. These heavy-lift ambitions require specialised, high-capacity thrust stands capable of measuring forces of millions of pounds. In fact, Interface has actually engineered “million-pounder” load cells for this very reason.

Finally, the pivot toward green and electric propulsion means modern rigs must be sensitive enough to measure the subtle whisper of an electric ion thruster in a vacuum, just as accurately as the roar of a chemical booster.

As the 21st-century race to space accelerates, the requirement for precision becomes the ultimate gatekeeper for innovation. Whether it is a commercial start-up launching its first small-sat or a global space agency preparing for deep-space colonisation, the data gathered on a thrust stand is the foundation of every successful mission.

Interface continues to lead this charge, providing the gold-standard sensor technology that enables engineers to push the boundaries of what is possible, ensuring that every Newton of force is accounted for and every structural limit is understood. By bridging the gap between raw propulsion and actionable intelligence, Interface doesn’t just measure force; we enable the next giant leap in human exploration.

On land, farming equipment must cope with uneven terrain, variable soil resistance, and constantly changing loads. Force measurement sensors allow operators and designers to understand exactly how machinery behaves in real‑world conditions.

Load cells and torque transducers are commonly integrated into tractors, harvesters, and transport carts. By monitoring forces in real time, farmers can optimise fuel consumption, avoid overloading equipment, and improve crop handling processes while reducing mechanical stress and downtime.

Video: Sensors for farming on land

How can PTO torque be measured in agricultural machinery?

The Power Take‑Off (PTO) shaft transfers power from a tractor to implements such as ploughs, seeders, and balers. Measuring PTO torque provides valuable insight into how much force is required to operate equipment under different soil and crop conditions.

Using a rotary torque transducer on the PTO allows engineers to capture dynamic torque data during operation. This helps evaluate efficiency, detect overload conditions, and refine implement designs. By understanding torque behaviour, manufacturers and farmers can improve reliability, reduce fuel use, and extend equipment life.

How do sensors improve smart grain transport management?

Transporting grain efficiently requires accurate weight monitoring. Overloaded carts increase fuel consumption, damage infrastructure, and reduce safety. Under‑loading wastes time and capacity.

Load cells mounted on grain carts and trailers provide continuous weight data during filling and transport. Combined with software systems, operators can optimise loading, monitor distribution, and improve logistics efficiency. This approach supports precision agriculture by reducing waste and improving productivity across large operations.

What role do sensors play in robotic weeding and precision crop management?

Robotics is transforming agriculture through automated planting, harvesting, and weeding. These machines rely on force feedback to interact safely with crops and soil.

Multi‑axis force sensors allow robotic tools to sense resistance when removing weeds or handling delicate plants. In vertical farming and automated crop systems, this feedback ensures consistent pressure is applied, preventing crop damage while improving accuracy. Force measurement enables robots to adapt dynamically to changing conditions in the field.

What sensor solutions support aerial farming using drones?

Drones are increasingly used for crop spraying, mapping, and monitoring. Their effectiveness depends on stable flight and precise payload control.

Force measurement sensors help engineers understand the mechanical stresses acting on UAV structures and payload systems. By measuring lift, drag, and weight changes, designers can optimise drone performance, improve safety, and increase operational efficiency in aerial farming environments.

Video: High flying innovation with UAVs – farming in the air

How are spray drone payloads calibrated using load cells?

Spray drones carry liquid tanks that change weight and centre of gravity as fluid is released. This shifting mass can destabilise flight if not properly controlled.

Load cells integrated into payload systems measure real‑time weight and slosh effects. This data allows control systems to adjust thrust and balance dynamically. Accurate payload measurement improves spray consistency, flight stability, and battery efficiency during agricultural drone missions.

How do multi‑axis sensors test UAV structural stress?

During drone development, engineers must understand how structures respond to aerodynamic forces. Multi‑axis sensors capture forces and moments across several directions simultaneously.

Measuring robot performance in autonomous delivery systems: why torque testing matters

Autonomous delivery robots are no longer a futuristic concept. From university campuses in the US to growing trials across the UK, these robots are already being tested in real-world environments where they must navigate complex routes, avoid obstacles, and transport goods safely and efficiently.

Behind every successful autonomous robot is rigorous engineering and testing. For design engineers, one of the key challenges is how to accurately monitor and measure robot performance, particularly when it comes to movement, load handling, and safety. This is where torque measurement and testing play a critical role.

The engineering challenge of autonomous delivery robots

Delivery robots operate in environments that are unpredictable and constantly changing. Typical challenges include:

• Navigating narrow pathways and busy pedestrian areas
• Detecting and avoiding static and moving obstacles
• Travelling over varying terrain such as slopes, kerbs, and uneven surfaces
• Carrying food or packages securely without spillage or damage

Each of these factors places mechanical and electrical demands on the robot’s drive system. Engineers must ensure that motors, gearboxes, and wheels work together efficiently — and safely — under all expected operating conditions.

Why measuring torque is critical in robot design

Torque is a fundamental parameter when designing and validating robotic mobility systems. It directly influences how a robot accelerates, climbs slopes, carries loads, and responds to resistance.

By measuring torque during development and testing, engineers can:

• Validate motor and drivetrain selection for real-world operating loads
• Ensure consistent performance when carrying varying payloads
• Identify inefficiencies or excessive mechanical stress in gearboxes and joints
• Improve safety, particularly when robots interact with people in public spaces

Without accurate torque data, robots may struggle with mobility, experience premature component wear, or pose safety risks during operation.

Monitoring robot performance in real-world testing

During testing, torque measurement allows engineers to compare expected performance with actual behaviour. For example:

• How much torque is required when the robot starts moving from rest?
• How does torque change when navigating inclines or uneven surfaces?
• What happens to torque demand when the robot is fully loaded versus empty?

These insights help engineers refine control algorithms, optimise energy efficiency, and ensure reliable operation over long periods of use.

For autonomous delivery robots operating continuously throughout the day, even small improvements in efficiency or mechanical design can result in significant gains in reliability and battery life.

From campus delivery to UK trials

While early deployments of food delivery robots have been seen on university campuses in the US, similar technologies are now gaining momentum in the UK. Trials of autonomous delivery robots — and drones — are underway in selected areas, including towns such as Darlington.

As these systems move closer to widespread adoption, the demand for robust testing and measurement will only increase. Public environments require exceptionally high standards of safety, repeatability, and performance — all of which depend on accurate measurement during the design and validation stages.

Real-world UK trials of autonomous delivery

Across the UK, autonomous delivery technologies are moving beyond pilot stages. Companies such as Evri are trialling wheeled-legged robots to handle “last 100-yard” parcel delivery in Barnsley — tackling kerbs and uneven terrain with AI-driven navigation.

In Greater Manchester, Trafford Council has expanded robot delivery services that navigate pavements using sensor-based mapping and obstacle avoidance.

Retailers including Co-op have deployed Starship robotic grocery deliveries across Yorkshire, with thousands of households now able to schedule autonomous drop-offs via app.

On the aerial side, Amazon has begun test flights from its Darlington fulfilment centre as it prepares for the first UK drone deliveries under its Prime Air service — working with local authorities and the Civil Aviation Authority to bring autonomous drones into public use.

The role of torque sensors in robotics testing

High-quality torque sensors enable engineers to capture precise, repeatable data from motors and drivetrains during both laboratory and field testing. When integrated into a test setup, they provide real-time insight into how a robot responds to load changes, terrain variation, and operational demands.

For robotics engineers, this data supports:

• Faster design iteration
• Improved confidence in system performance
• Reduced risk during deployment in public spaces

Designing safer, more reliable autonomous robots

Autonomous delivery robots must do more than simply move from point A to point B. They must do so safely, efficiently, and consistently, even in challenging environments.

By incorporating torque measurement into the design and testing process, engineers gain the data they need to optimise mobility, protect mechanical components, and ensure safe interaction with the public. As robot delivery trials expand across the UK, this type of performance monitoring will play an essential role in turning promising prototypes into reliable, real-world solutions.

The world relies on minerals. From the lithium batteries in our electric vehicles to the rare earth elements in our smartphones and the cobalt in renewable energy systems, the demand for these essential resources is sparking a revolution in the global mining industry.

The new era in mining requires more than just larger trucks and deeper pits. Modern mining demands precision, safety, and operational intelligence to achieve ambitious production targets efficiently and responsibly.

Interface advances mining predictability, production, and safety with our sensor technologies. Our load cells, torque transducers, multi-axis sensors, instrumentation, and wireless telemetry solutions help transform the way we extract our natural resources. By integrating real-time data from these sensors into critical equipment and infrastructure, the measurements support smart, data-driven mining operations.

 What makes the current mining era more risky – and more rewarding?

The pressure on the modern mining industry is unprecedented. Historically, mining has faced challenges related to safety, unplanned downtime, and low efficiency. Now, the stakes are higher due to the global reliance on mining production.

The energy transition depends heavily on a consistent supply of mined materials. Delays or inefficiencies in extraction can have widespread effects on the global economy. A major challenge is the traditional lack of real-time monitoring of huge mechanical forces. Without continuous data on stress, torque, and load, operators struggle to identify potential overloads and failures before they occur. This increases the risk of accidents and results in costly, unexpected downtime. Interface is a long-term provider of vital measurement solutions used across various mining applications, from heavy-duty lifting equipment to scales for weighing mineral outputs.

The global smart mining market is expected to exceed $34 billion, showing the rapid adoption of digital technology. Sensors are the backbone of this digital mine, supporting everything from predictive maintenance to autonomous operations.

Five advanced mining use cases and applications supported by Interface Solutions

 Whether it is installing load cells into material movers and conveyors for safety, precisely monitoring the weight of materials in tanks and material movers, or ensuring that quality ATEX-approved sensors are used in environmentally hazardous applications, Interface is a preferred supplier of these types of sensor technologies.

 #1 – How intelligence can be embedded into heavy mining machinery

Interface offers rugged, proven sensor technologies, including load cells, torque transducers, load pins, and shackles, along with wireless systems that withstand the most challenging mining conditions while delivering highly accurate data. This information provides operators and engineers with actionable insights needed to manage quality, monitor safety, and extend asset life.

#2 – How do our sensors improve the performance and longevity of excavators? 

Excavators are force-intensive machines. Interface sensors measure the digging force applied by the bucket to ensure optimal penetration for specific materials, preventing unnecessary wear and improving energy efficiency. Torque transducers measure the swing torque, verifying sufficient rotational power for safe and effective material movement. This data is essential for optimizing machine design and increasing energy efficiency.

#3 – How are truck scales & logistics optimised to prevent overload and wear? 

Overloaded haul trucks significantly increase maintenance costs, safety risks, and fuel consumption. Interface WTS 1200 Low-Profile Load Cells easily integrate into weighing scales. As a loaded truck passes, they measure and wirelessly send accurate weight data to a base station. This real-time information helps ensure compliance with load regulations, reducing mechanical stress and prolonging the lifespan of tires and chassis.

Every year, Santa Claus faces the monumental task of making sure every child’s present is ready, wrapped, and dispatched in time for Christmas Eve.  But did you know that this year, Santa has an extra secret weapon in his workshop? Enter Semota — the real-time remote monitoring platform that tracks the flow of Christmas magic.

Santa’s workshop, upgraded

In Santa’s North Pole factory, elves hustle and bustle, placing toys on a giant conveyor belt. This belt snakes through the workshop, carrying every kind of present you can imagine — from teddy bears to model trains. Santa and his elves want to make sure nothing goes wrong: no toy is left behind, no belt stalls, and no “naughty list” order gets missed.

That’s where Semota’s industrial monitoring capabilities come in. By strategically placing Semota sensors along the conveyor line — at key points where presents enter, where they’re inspected, boxed, or packed — Santa can monitor the entire operation in real time.

What Semota actually does in this scenario

Real-time status updates: Semota’s live dashboard shows exactly how fast toys are moving, where they might be building up, and whether any part of the belt is slowing down or stopping.

Alerts & alarms: If a section of the belt spikes in temperature (maybe because the elves’ soldering tools are running hot) or slows unexpectedly, Santa gets instant alerts on his phone or tablet.

Historical data: He can look back at trends — maybe there’s a pattern where certain types of presents (like rocking horses) always take longer at that inspection station. Because even in the North Pole, data-driven decision making is the key to productivity.

Proactive maintenance: With this insight, Santa’s maintenance elves can prevent breakdowns before they happen, ensuring the belt doesn’t jam on Christmas Eve.

The elf angle – Santa’s data analysts

Of course, elves are more than helpers — they’re engineers, quality controllers, and logistics managers. Some elves are stationed at key “sensor stations,” checking metrics from Semota, waving to Santa when everything’s green, or calling for support when something trips an alert. There might even be an elf dedicated to “data elfing” (that’s data + elf, get it?) — ensuring the dashboard is always up to date.

Christmas cheer + efficiency

Using Semota doesn’t just make Santa’s workshop more efficient; it gives him peace of mind. On Christmas Eve, when time is tight and the pressure is on, Santa’s not just relying on old-school magic — he’s relying on technology. With Semota, he can see his operation at a glance, make data-driven decisions (“Elf, redirect that batch of plushies”), and make sure every gift makes it out on time.

Why this matters for your business (or readers)

Modern story: It’s a fun, modern metaphor for how remote monitoring can optimise any high-volume, mission-critical process.

Relatability: Even though our “Santa’s workshop” is fictional, the challenges he faces (bottlenecks, maintenance, quality control) are very real in industry.

Showcasing Semota: This story highlights how Semota helps with real-time visibility, alerting, and trend analysis — all things that are invaluable in manufacturing, logistics, or mission-critical operations.

Semota remote monitoring – how to find out more

So, this Christmas, while Santa is checking his list (twice), he’s also checking his Semota dashboard. And if you’ve got a process — holiday-themed or not — that could use better visibility and smarter monitoring, maybe it’s time to give Semota a spin. After all, if it works for Santa’s North Pole belt, it could work for you too.

What are the core measurement challenges in animatronics and entertainment robotics?

The world of animatronics is no longer just for old-school theme park rides or B-list sci-fi movies. Animatronics are complex mechatronic systems that require precise control to achieve lifelike movements and ensure safety. This control isn’t a one-time setup, but a continuous process of measurement, feedback, and adjustment.

In animatronics, the control system, acting as the “brain,” uses sensors as its “eyes” and “ears,” providing real-time data on position, force, and torque. This feedback loop allows the system to make tiny, instantaneous adjustments to maintain the desired movement, much like a human balancing a pen on their finger.

Animatronics is a dynamic field of entertainment. It is a fusion of puppetry, anatomy, mechatronics, and robotics, and it is experiencing explosive growth, with a market projected to reach over $18 billion by 2032.  The magic behind this expansion lies in technological advancements and the increasing demand for immersive, interactive experiences supported through high-accuracy force, torque, and weight measurements.

How do sensors enable lifelike movement and safety in animatronics?

At the core of modern animatronics are sensors that are crucial for achieving realistic, reliable, and safe motion capture performance. They are used throughout the entire lifecycle, from design and prototyping to real-time monitoring. The detailed orchestration of simulation requires the precision of measurement that load cells, torque transducers, multi-axis sensors, and load-measuring pins provide.

Interface force and torque sensors are embedded within the animatronics framework. They provide real-time data on movement and force, allowing the figure to react dynamically to its environment and even to people. This creates a more natural and engaging interaction.

Which force, torque, and multi-axis measurement technologies are used in entertainment robotics?

Load cells and torque transducers help to ensure that the movements of animatronic limbs and components stay within safe operating limits. This prevents damage to the expensive equipment and, more importantly, protects nearby individuals. It’s a vital part of both the initial design validation and ongoing maintenance. Continuous monitoring with load cells and instrumentation provided by Interface can aid in the long-term success of animatronics. The data helps engineers calibrate movements, maintain peak performance, and identify potential issues before they lead to mechanical failure. This proactive approach ensures the equipment runs smoothly for its entire lifespan.

Where are sensor-enabled animatronics used beyond theme parks?

Animatronics are expanding their reach across the entertainment industry, going beyond just theme park attractions.

• Amusement and theme parks have adopted animatronics at a rapid pace. From classic rides to new, immersive worlds, animatronics create unforgettable, interactive experiences. From hyper-realistic immersive environments to autonomous robotic creatives performing complex acrobatics, parks are providing a modernised level of entertainment.
• Special effects in film and television provide a tangible realism that digital effects sometimes struggle to match. They allow fantasy creatures and robotic characters to have a physical presence on set, interacting with actors and their environment in a way that feels unquestionably real.
• Interactive experiences are now used in museums, retail spaces, and public venues to engage audiences with dynamic displays. Beyond entertainment, they’re also being used in consumer products, such as robotic pets for therapy, and are being explored in fields like education and healthcare.

The need for precise measurement and control extends to all aspects of animatronics, from movie magic to theme park thrills and even robotic bartenders. For example, measuring the torque of a motor or a joint is crucial. It ensures the animatronics’ limbs have enough force to move a prop or character, but don’t exceed safe limits that could cause damage or injury.

Creators and engineers use force and torque measurement solutions to test these movements during design and ongoing maintenance, proving that as animatronics become more complex and interactive, the role of precise test and measurement will only grow.

How is measurement data used for design validation and ongoing maintenance of entertainment robots?

Animatronics must deliver accurate, repeatable, and safe movements. A key challenge is measuring the torque of the motors and joints that power these movements to ensure proper calibration and prevent them from exceeding safe limits. This testing is vital during the design phase and for ongoing maintenance.

In an animatronics test lab, Interface’s MRTP Miniature Overload Protected Flange Style Reaction Torque Transducer was connected to the servo motors in the limbs of the animatronics that make it move. The customer monitoring the animatronics viewed torque results on their PC when the transducers are connected to the BX8-AS BlueDAQ Series Data Acquisition with Industrial Enclosure. Using this setup, the customer was able to record the force results of his metal-bending machine with Interface’s Wireless Telemetry System.

Event venues can utilise animatronics for entertainment and create immersive experiences. An efficient alternative to tradition is robotic bartenders. However, force testing is required to detect subtle shifts in shaking and pouring mechanics to prevent spillage or error. Interface’s 6A40 6-Axis Load Cell measures force and torque along several directions simultaneously, vital for accurate drink preparation under dynamic conditions. The testing results can be logged, displayed, and measured when connected to Interface’s BX8-HD44 BlueDAQ Series Data Acquisition System with included BlueDAQ software.

The future of animatronics is brighter and more lifelike than ever, blending cutting-edge robotics and AI with artistic vision to create magical, memorable, and safe experiences.

I was visiting a customer recently when someone asked me, “What’s the most unusual thing you’ve ever pressure-mapped?”

It’s a fair question — after all, since Interface began supplying XSensor’s advanced pressure mapping systems and sensors back in 2007, I’ve tested everything from tyre footprints and car door seals to beds, seating, and surgical equipment. But one project stands out from all the rest — and it involved high heels, a TV studio, and comedian Lee Mack.

Sky TV had contacted us about a segment for their show Duck Quacks Don’t Echo, a comedy science programme where celebrity guests present unusual facts or theories that get tested live on air. My task? To measure and compare the pressure exerted on the ground by a heavy soil compactor (a rammer) and a pair of women’s stiletto heels.

The theory, proposed by presenter Lorraine Kelly, was that a woman in high heels would exert more pressure per square centimetre than the rammer. And as the resident expert, I was asked to come on the show to measure the pressure from the working Rammer, then from Lorraine Kelly in a pair of stilettos.

Coming on TV to stand next to a roaring rammer and then measuring pressure beneath a pair of stilettos wasn’t exactly what I was expecting to do that day. Not a typical day at the office! But it certainly made for great television — and even better science.

And in case you’re wondering: yes, Lorraine Kelly’s heels really did out-press the rammer.

The artist and film producer, Andy Warhol, once said that in the future, everyone will get fifteen minutes of fame. Mine came — and went — in a flash of stilettos and soil compactors.

FAQ: Understanding the Science Behind Pressure Mapping

Q: What is “Pressure Mapping?”

A: Pressure mapping is the process of measuring and visualising the distribution and magnitude of force (pressure) over a specific contact area. It uses specialised sensors to create a high-resolution “map” showing where the most and least pressure is being applied. This is crucial for things like designing comfortable seating, analysing tyre footprints, or, in this case, comparing the force of a stiletto heel to a rammer.

Q: What is a “Rammer” (or Soil Compactor)?

A: A rammer is a heavy-duty machine used in construction and groundwork to compact soil, gravel, or other materials. It works by repeatedly dropping or driving a heavy plate onto the ground, exerting a significant total force. The article specifically refers to a heavy soil compactor.

Q: What is the difference between “Force” and “Pressure per Square Centimetre?”

A: This is the core concept of the experiment!

• Force is the total push or pull on an object (like the total weight of the rammer or the person in the heels).
• Pressure is the force distributed over a specific area. The formula is: $Pressure = \frac{Force}{Area}$.

A rammer applies a large total force, but a stiletto heel concentrates a person’s weight into a tiny area (the heel tip). By dividing the force by that tiny area, the pressure ($\text{force/area}$) of the stiletto can dramatically exceed that of a much heavier machine!

Q: What is the XSensor IX510:64.64.04 Stance Pad Sensor?

A: This is the specific tool used to measure the pressure.
– XSensor is the brand of advanced pressure-mapping technology used by Interface.

• The Stance Pad Sensor is a large, mat-like sensor designed to measure the pressure distribution under a person’s feet (their “stance”). The numbers (like 64.64.04) refer to the density and type of sensors within the pad, ensuring high accuracy for both a rammer’s base and a small heel.

What is moment compensation?

Moment compensation is a fundamental engineering principle that ensures stability and accuracy by counteracting unwanted forces. While its importance is clear in a lab setting, its impact carries over into high-stakes industries where precision is non-negotiable.

At Interface, the moment compensation principle is a core part of our load cell design best practices, making our force measurement solutions a decisive component in some of the world’s most demanding applications.

What are the benefits of Interface’s Moment Compensation for Force Measurement?

Our LowProfile Load Cells are moment compensated to provide the highest possible accuracy, even when loads are off-axis. This is achieved through a meticulous process that goes beyond standard industry practices. We deliberately load each cell eccentrically, monitor and record the output signal, and then make internal adjustments to minimise errors.

Unlike many manufacturers who use a basic four-gauge design, we employ eight strain gauges strategically placed on our radial flexure beams. This configuration, combined with our rigorous compensation process, allows our load cells to detect and counteract the effects of extraneous forces, ensuring a more precise and reliable measurement.

Moment compensation improves the stability of a load cell, particularly in situations where the load is off-centre or subject to torque. This can prevent the load cell from shifting or becoming damaged, leading to more consistent and reliable measurements.

Video:

For a technical dive, watch our video Moment and Temperature Compensation – Load Cell Performance Starts By Design Webinar.

Now, let’s explore how our moment-compensated products enable success in three key industry uses: aerospace, robotics, and structural testing.

How does moment compensation enable success in aerospace applications?

In aerospace, even the smallest error can have monumental consequences. Every component, from a jet engine to a satellite part, undergoes rigorous testing where forces, weights, and torques must be measured with absolute accuracy. Off-axis loading from a shifting engine on a test stand or the subtle vibrations of a wing during a fatigue test can introduce moments that skew data.

This is where Interface’s LowProfile™ Load Cells prove invaluable. Their unique radial design and use of eight strain gauges are specifically engineered to minimise sensitivity to extraneous loads and torques. This allows aerospace engineers to:

• Accurately measure thrust, isolating the pure axial force of an engine from the influence of side loads and vibrations.
• Conduct precise structural testing on airframe components, even when the test setup isn’t perfectly aligned.
• Validate and calibrate flight simulators, providing the clean, reliable data needed for critical system validation.

How does moment compensation ensure safe and smart robotics and automation machines?

The world of robotics relies on a delicate balance of power and exactness. A robotic arm needs to “know” exactly how much force it’s applying to avoid crushing a fragile component or dropping a heavy one. A moment created by a sudden stop or a change in the weight of a gripped object can cause a robot to fail its task.

Interface offers a range of sensors that provide the reliable data robotic control systems need to succeed. Our multi-axis sensors and moment-compensated load cells give robots a sense of touch, enabling:

• Precision gripping, where a sensor at the end of an arm accurately measures and adjusts the force to prevent damage.
• Automated assembly, ensuring parts are pressed into place with the exact force required, free from the errors moments can cause.
• Real-time feedback, allowing the robot to make instant adjustments in dynamic environments, is crucial for both efficiency and safety.

How does moment compensation help with structural testing?

Engineers design bridges, buildings, and vehicles to withstand immense forces. To test the strength of materials and components, they must create flawless test environments. Any off-axis loading from a test fixture or a slight misalignment can introduce a moment that compromises the test data. This could lead to a flawed design or cause excellent material to fail a test unnecessarily.

Interface’s reputation for superior moment compensation makes our products the go-to solution for structural testing. Our high-capacity load cells are built to withstand and compensate for eccentric loads, guaranteeing that the measured force is an accurate representation of the material’s strength. This allows engineers to:

• Conduct reliable tension and compression testing, ensuring a pure, on-axis force measurement despite minor imperfections in the test specimen.
• Perform long-term fatigue testing with confidence, knowing our sensors will provide stable and repeatable measurements over millions of cycles.
• Verify the quality of products by ensuring they meet rigorous safety and durability standards.

A Differentiator for Every Challenge

Moment compensation is not just a technical feature for load cells. It’s a core design philosophy that makes Interface products a trusted solution across a wide range of industries. Our commitment to this principle allows us to deliver unparalleled accuracy and reliability in the world’s most demanding applications.

Interface guarantees maximum extraneous load error and physically adjusts every load cell. The Interface 1200 Series cells have eccentric load sensitivity less than ±0.25% of reading per inch, and the 1000, 1100, and 1600 Series are further adjusted to come in at less than ±0.1% of reading per inch. Most competing load cells will have an extraneous load error 10 times higher (or even more) than with a superior Interface load cell.

In the world of heavy lifting, precision is essential. Whether lifting massive steel beams, shipping containers, or critical aerospace parts, cranes are vital for these tasks.

Ensuring these complex operations are performed securely and efficiently requires advanced technology both in the crane design itself and in the associated equipment used to lift and move objects. Load cells, used to measure force and weight, are a key solution for successful crane operations.

Interface Force measurement solutions, including load cells, load pins, tension links, and load shackles, as well as wireless systems, indicators, and data acquisition instruments. These are valuable devices for monitoring loads, preventing overloads, and protecting both personnel and equipment.

Can load cell technology improve safety of crane operations?

At the core of load cell sensors is a simple, yet ingenious principle: the conversion of mechanical force into a measurable electrical signal. Interface products utilise strain gauges for accurate measurement data.

When a heavy object is lifted, it applies a force to the load cell’s body, causing a minute deformation or “strain” in the metal. Strain gauges, which are tiny wires bonded to the load cell’s body, are sensitive to this deformation. This change in resistance is measured by a Wheatstone bridge circuit, which converts the resistance change into a proportional electrical voltage. This voltage is then transmitted to a display or control system, providing a real-time, accurate measurement of the load’s weight.

Accurate and reliable load cell data helps operators make informed decisions and keeps operations within a crane’s rated capacity.

In the demanding world of oil and gas exploration, precision and reliability are non-negotiable.

Topside measurements often fall short in deep, deviated, or horizontal wells, making accurate downhole data a critical need.

Interface, a trusted leader in force measurement for the energy industry, has engineered a solution to this long-standing problem: the Interface Pressure Compensated Downhole Load Cell (IPCD). This innovative product provides accurate, real-time force measurement directly at the source, overcoming the limitations of traditional technologies.

What is the problem with traditional “wet” load cells?

For years, the industry has relied on “wet” load cells for downhole force measurement. These systems use a hydraulic compensation method with pistons and seals to counteract the immense pressures found deep underground. However, this approach comes with significant drawbacks:

• High Maintenance and Cost: The moving seals in wet load cells create friction and error, and they require frequent replacement. This leads to high service costs, tool disassembly, and costly downtime.
• Reduced Accuracy: The hydraulic compensation exposes the strain gages to silicon oil, which shortens their lifespan and compromises data accuracy.
• Limited Application: Wet load cells rely on above-ground readings, making them ineffective for horizontal wells, which have become increasingly popular with the rise of fracking.

What is the best solution for accurate downhole data?

The Interface IPCD load cell offers a superior alternative. Interface’s proprietary internal compensation method allows the device to actively measure only the axial force, while completely ignoring the effects of high pressure and temperature. This groundbreaking approach provides several key advantages:

• Exceptional Accuracy and Reliability: The IPCD is a Wheatstone bridge, foil-gaged-based solution that is fully compensated for both pressure (up to 20,000 PSI) and temperature (up to 400°F). It delivers world-class linearity and hysteresis, ensuring highly accurate and repeatable data. The design is also incredibly robust, with a 30,000 lbf safe load rating and a 90,000 lbf ultimate load rating.
• Maintenance-Free Design: Unlike wet load cells, the IPCD is a self-contained, completely analogue solution. The internal compensation eliminates the need for a pressure vessel and moving parts, making it a “maintenance-free” solution that reduces long-term costs and downtime.
• Expanded Applications: The IPCD can be used in both vertical and horizontal wells. It’s ideal for a wide range of oil and gas applications.

Downhole drilling use cases

Deviated and lateral wells render topside measurements of little value. Successful pump down services require accurate tool string tension readings, downhole, at the source. The IPCD Pressure Compensated Downhole Load Cell is a precise and reliable load cell that Interface has explicitly developed for downhole tension and compression measurements in high-temperature, high-pressure well conditions.

How does a downhill load cell work?

1. The IPCD Pressure Compensated Downhole Load Cell is integrated near the top of the tool string.
2. During pump down, the IPCD measures the tension between the cable head and the tool string.
3. Connected to the customer’s instrumentation, actual cable head tension is closely monitored across any variation of temperature or pressure.

Featuring proprietary pressure and temperature compensation, precise tool string force measurements can be monitored in real time through customer instrumentation. The solutions provide control of the pumping forces on the tool string with incredible accuracy. Regulating this process ensured service success without the risk of tool pump off, avoiding a devastating and expensive fishing operation.

How do load cells work in a horizontal well application?

When a pumpdown operation is used for horizontal wells in the oil field, fluid is pumped to push tools down the deviated or horizontal wells. Operations could include plug setting and perforation. Accurate tool string tension readings are required for this downhole procedure. The IPCD Pressure Compensated Downhole Load Cell is a correct and superior load cell over wet or hydraulically compensated load cell options. Featuring proprietary pressure and temperature compensation, offering precise and real-time tool string force measurements. You can learn more about this use case in the Wireline Pump Down Application Note.

How can an IPCD load cell operate in a ruggedised downhole  environment?

Each IPCD load cell is individually tested to meet the rigorous demands of the downhole environment, with comprehensive testing for force, creep, pressure, and temperature. While the IPCD is not currently NACE compliant for sour gas applications, custom solutions can be designed to meet specific needs.

By providing a durable, high-performance, and maintenance-free solution, the Interface Pressure Compensated Downhole Load Cell is setting a new standard for force measurement in the oil and gas industry.

Interface leverages experience, engineering design, and production skills to provide standard model solutions. It should be noted that there is still an option to modify the IPCD Load Cell and customise it to adapt to customer hardware.

Interface stands out by offering ruggedised, high-accuracy load cells specifically designed for the oil and gas sector’s demanding environments. Interface helps the energy market with force measurement solutions specially developed for harsh conditions, with sensors that can withstand up to 30,000 psi and 500 degrees Fahrenheit.

When it comes to head protection, the stakes couldn’t be higher. Traditional helmet testing methods—using drop tests and accelerometers—measure peak acceleration forces during an impact.

While this provides valuable safety data, it doesn’t reveal how those forces are distributed across the head. A helmet might pass certification while still allowing dangerous localised pressure “hot spots” that increase the risk of injury.

This is where pressure mapping comes in. By capturing detailed pressure distribution inside the helmet during impact, manufacturers gain a deeper understanding of how their designs perform—far beyond the limits of standard testing.

Going Beyond Traditional Testing

Conventional certification standards for helmets—whether bicycle or motorcycle—focus on criteria such as peak headform acceleration, chinstrap strength, penetration resistance, and roll-off stability. While effective, these tests often provide only part of the picture.

Pressure mapping, using systems such as the XSensor High Speed (HS) Impact System combined with thin, conformable sensor arrays, allows engineers to measure:

• Peak and mean pressure across the headform surface.
• Contact area and movement of high-pressure zones.
• Pressure gradients, which can indicate areas of concentrated load.
• Pressure-time integrals, showing cumulative load during impact.

The result is precise, high-resolution data that highlights how impact energy is distributed—and where helmet designs can be improved.

Testing Bicycle vs Motorcycle Helmets

 Bicycle Helmets

Standards such as CPSC (USA), EN 1078 (Europe), and AS/NZS 2063 (Australia/New Zealand) require impact testing at lower velocities (around 5–6 m/s). Tests include drop impacts onto flat, hemispherical, or kerbstone anvils, as well as retention and roll-off checks.

While these methods set minimum safety requirements, pressure mapping provides an extra layer of insight—helping designers reduce concentrated load points, improve liner optimisation, and enhance comfort.

Motorcycle Helmets

Motorcycle helmets are subject to more demanding standards, including DOT FMVSS 218 (USA), ECE 22.06 (Europe and beyond), Snell M2020, and JIS T 8133 (Japan). These involve higher-energy impacts (7–8 m/s), penetration tests, multiple impact sites, rotational impact studies, and environmental conditioning (hot, cold, wet).

Here, pressure mapping demonstrates particular value, as it can reveal localised high-pressure zones even when overall acceleration readings remain within limits. This is especially relevant in modern rotational injury studies and for validating computational helmet models.

Global Standards Snapshot

Helmet manufacturers face a wide landscape of safety regulations:

• CPSC (USA) – mandatory for all bicycle helmets sold in the U.S.
• EN 1078 (Europe) – covers bicycles, skateboards, and roller skates.
• AS/NZS 2063 (Australia/NZ) – generally more stringent.
• DOT FMVSS 218 (USA) – self-certified motorcycle helmet standard.
• ECE 22.06 (Europe/International) – includes oblique/rotational testing.
• Snell Standards (Voluntary) – stricter impact and penetration criteria.
• FIM Racing Homologation – for professional racing, includes advanced rotational and environmental tests.

Pressure mapping is not yet mandated by these standards, but it is rapidly becoming a critical tool in R&D for manufacturers seeking competitive advantage in safety, performance, and rider comfort and ultimately and most importantly rider safety.

Why Manufacturers Should Adopt Pressure Mapping

For helmet makers, the benefits are clear:

• Better product differentiation through enhanced safety and comfort.
• Faster R&D cycles, with accurate data guiding design refinements.
• Improved confidence when validating helmets against global standards.
• Insight into rotational and localised impact behaviour that traditional methods cannot provide.

By integrating XSensor’s HS Impact System and flexible, durable sensor mats into their testing process, manufacturers can push beyond compliance and towards innovation—delivering helmets that not only pass certification, but also provide superior protection where it matters most.

Space travel is one of the most intriguing pursuits in modern culture and enormous investments have been made to reach the dream of navigating the final frontier.

From government to private entities such as SpaceX and Blue Origin, the colonisation of celestial bodies is becoming a real possibility, maybe even in our lifetime. However, what most people don’t think about when discussing the journey into space is the vast amount of different technologies that go into developing a spacecraft. This case study provides insight into how force measurement and Interface play a large role in the development of spacecrafts. It includes a brief overview of the customer challenge and examples of Interface solutions used to optimise spacecraft and other aerospace product designs.

Challenge

There are hundreds of thousands of moving parts in the space industry that need to be optimised for a successful launch. From the thrust of a rocket engine to the structural integrity of the craft’s landing gear, the hardware goes through test after test to ensure that everything is built to specifications, performs at a high level, and is reliable over time. Any tiny miscalculation or error in the design, manufacturing and testing of this equipment can become costly, and more importantly, unsafe to the astronauts and crew.

One of the key test processes that occur during the development of a spaceship is force measurement testing. Companies in the aerospace industry involved in space travel must understand various aspects of the force, compression, torque, and tension that materials and components used in the design of a spacecraft can withstand or output. For instance, thrust is a critical factor in providing enough speed to launch a vehicle out of the earth’s atmosphere. Data on the power of a rocket engine’s thrust is calculated with force sensors. Another design consideration in a spacecraft is the structural integrity of the fuselage and wings. These are also pieces of hardware that can also be analysed using force measurement devices.

Ultimately, optimising a spacecraft’s design involves testing a lot of moving parts that all interact differently when introduced to stressors during the launch sequence. Companies in the aerospace industry have turned to force measurement to gather accurate data on these systems, processes, and materials.

Interface Solutions

Interface offers a wide variety of load cells, torque transducers, load pins, and load shackles, and digital instrumentation to collect data and improve the design, manufacturing, and most importantly, the testing process for spacecrafts. Interface’s work in space is on display in testing labs, manufacturing facilities and even launch sites worldwide. Included below are a few examples of real applications of force measurement in space:

Structural Testing – Real-life application

Structural tests are critical to the launch process because the craft’s core components, such as the liquid hydrogen and oxygen tanks, wings, and fuselage, must withstand launch loads of up to nine million pounds of force (lbf). Recently, NASA’s Space Launch System (SLS) used Interface load cells to measure the core stage of the rocket. This particular core stage is one of the largest ever built at 27 feet in diameter and more than 200 feet tall.

To perform the structural test, Interface supplied its 1200 High Capacity Standard Precision LowProfileTM Load Cells, which were attached to hydraulic cylinders at various locations along the rocket test stand to provide precision test forces. Strain gauges were also bonded to the rocket structure surface and connected to a data acquisition system for stress analysis. NASA engineers were able to measure loads applied at various areas on the rocket structure, verifying the structural performance under simulated launch conditions.

Thrust Testing – Real-life application

A rocket that is fully fuelled and ready for launch can weigh up to five million pounds. Therefore, the force necessary to lift the rocket out of the earth’s atmosphere is immense. There are several other factors working against the rocket which need to be compensated for when adjusting thrust force such as drag. Interface has supplied load cells to many aerospace customers to test force and other contributing factors for lifting a rocket into space. These load cells work by being installed underneath a test plate which the rocket engine will sit on. As the engine thrusts, the load cells will calculate the force output of the engine in real-time. This data is used to optimise the engine to determine how much thrust force is needed based on the spacecraft’s total weight and the calculated drag at lift-off.

Force Gravity Testing – Real-life application

Force measurement tools also serve many purposes outside of spacecraft testing in the aerospace industry. Interface was involved in a unique application of force measurement with a customer that wanted to develop a system to provide a full range of natural motion for a realistic simulation of reduced gravity environments. The system would be used to simulate weightlessness so astronauts’ crews could learn how to handle microgravity activities, including walking, running, and jumping. The system could also be used for surface operation studies, suit and vehicle development, robotic development, and mass handling studies.

In this application, Interface supplied a Model 1100 Series Load Cell, which was installed in-line with a steel support cable to actively measure the vertical load on the system. A control system was then utilised, (which includes a Model 9870 High Speed High Performance TEDS Ready Indicator), to monitor the load cell output and continuously offload a portion of a human or robotic payload weight during all dynamic motions. Using precise feedback from the load cell, the control system commanded a motor to raise or lower the subject to maintain a constant offload force. During the simulation, the system actively compensated for the subject’s movement to accurately reproduce a microgravity environment.

The pursuit of space is finding unique and innovative ways to traverse the star, carry more payload, and even find new places to inhabit. Hardware testing will continue to play a critical role in optimising and verifying this new technology, and force measurement is a significant part of this process. Interface has many systems and products available for aerospace applications. The company has been a trusted partner to some of the world’s largest space OEMs since the company’s advent more than half a century ago.

From dams to roads and bridges, the infrastructure industry is the backbone of our society and the need for sensor technologies used in the development and monitoring of these structures is never going away.

According to Forbes, the global infrastructure market sits at $3.6T. ReasearchandMarkets.com reports one of the largest Infrastructure sub-sectors, global construction, notes a compound annual growth rate (CAGR) of 9% from 2020 to 2021, with no slowing down. One of the factors accelerating growth is accurate and reliable test and measurement equipment, which is necessary to ensure durability, quality, and safety in all infrastructure projects.

Challenge

Safety and dependability of infrastructure is the most important factor in the design, development, and manufacturing of products in the industry. Buildings, bridges, dams, and more are expected to hold up over time and this makes it overwhelmingly necessary to engineer these structures to near perfection. Accurate and trustworthy equipment used for testing and actual construction is where we play a pivotal role. Take for instance the massive amount of design, engineering and quality control that goes into a suspension bridge requires testing before and after it’s built. Not only does it need to be constructed with supreme accuracy, it needs to be monitored constantly to ensure it’s safe for use, especially because infrastructure projects are exposed to extreme elements.

Interface Force is a supplier of choice to the infrastructure industry. Our engineers have designed products used for civil infrastructures, such as structural monitoring, vibrational monitoring, load bearing testing, tunnels, bridges, and road construction.

Infrastructure solutions

We provide a wide range of load cells, load pins and shackles, instrumentation, multi-axis sensors and torque transducers, which are top choices for infrastructure projects and testing with precision when quality matters most. Our sensor solutions are commonly used in measuring the related hardware used for industry products and structures.

The types of infrastructure projects that we have supplied measurement solutions for includes transportation systems, communication structures, water and electrical facilities, and numerous inventions that are used to build, support and maintain them.

The range of projects are broad, so we are highlighting a few below that highlight our capabilities when accuracy, quality and reliability matter in design, testing, construction and assessing current and limitations for safety requirements.

Hydropower turbine generator monitoring – Case study 1

A customer needed to monitor and detect any turbine generator faults in their hydroelectric power plant located on a river. Our solution was to use the T2 Ultra Precision Shaft Style Rotary Torque Transducer and attach it to the turbine generator with our Shaft Style Torque Transducer Couplings. When water from the river pushes through the penstock to the outflow, it moves the turbine blades, creating electricity through the generator shaft. Torsion measurements can be graphed and logged with the 9850 Torque Transducer and Load Cell Indicator catching any unusual fluctuations and vibrations. Using this solution, the customer was able to monitor, graph and log the torque measurement results of the turbine generator.

Aerial Lift Overload Control – Case study 2

A manufacturing company for aerial lifts wanted to test its self-propelled boom lift to ensure it could operate at heavy capacities when in use, and at different angles. The ultimate goal is to prevent any accidents in case of a lifting overload, for the safety of any working individual who uses it. We proposed attaching a 3A160 3-Axis Force Load Cell to the bottom of the bucket of the boom lift. The 3A160 3-Axis Force Load Cell gives high accuracy results and results could be displayed using the 920i Programmable Weight Indicator and Controller in real time. The company was able to use these products to test their aerial boom lifts and determined it was safely operable when maximum capacities has been reached.

Concrete Dam Flood Monitoring – Case study 3

A customer wanted to monitor and be notified if a concrete dam has reached high flooding levels. We proposed using WMC Miniature Sealed Stainless Steel Load Cells with multiple WTS-AM-1E Wireless Acquisition Modules connected to the dam. The WMC products are small in size and perfect for measuring tension and compression. Multiple WMCs were installed around the arch of the dam, so when flooding occurs, the WMC transmits data and notifies the customer through one of our Wireless Telemetry Systems.
