Digital Displays and indicators

The Interface Model 920i Programmable Weight Indicator & Process Controller is a severe-duty, legal-for-trade industrial indicator engineered to blend a highly flexible human-machine interface (HMI) with high-performance automated process control. Designed to manage everything from basic commercial weighing up to complex multi-stage batch automation loops, the 920i bridges the gap between traditional digital weight indicators, programmable logic controllers (PLCs), and computers. It is widely used across UK manufacturing lines, bulk material handling plants, vehicle check-weighing stations, and automated tank or silo batching yards where multiple independent data channels must be synchronised and verified simultaneously. 

The hardware architecture features a large, backlit LCD graphical display panel paired with an alpha-numeric 27-button keypad and five programmable soft keys, enabling technicians to quickly navigate custom menu configurations and clear operator prompts. For ultimate multi-sensor integration flexibility, the system expands via pluggable internal scale option cards to control and display data across up to 32 separate weighing systems concurrently.

The Interface Model 9325 Handheld Digital Indicator is a premium, battery and USB-powered portable device engineered for clear visual tracking of load cell measurements. Designed to interface seamlessly with load cells, and torque transducers, this handheld tracking unit accepts signal input sensitivities reaching up to ±1 V/V. It is widely specified across UK manufacturing test beds, lifting safety audits, mobile weighing inspections, and field diagnostics where laboratory-grade measurement resolution must go entirely mobile.

Equipped with an advanced 24-bit internal analogue-to-digital converter, the 9325 delivers a high internal resolution of up to 500,000 counts and a measurement rate reaching up to 2,400 readings per second. The last twenty TEDS devices connected can be remembered and recognised on this powerful yet small device. When they are connected again the 9325 will revert to the last user experience settings for that unit.

The Interface Model 9825 General Purpose Digital Display Indicator is a versatile, high-accuracy instrument engineered to translate low-level signals from any standard millivolt-per-volt (mV/V) sensor into clear, real-time data. Built with an intuitive internal matrix to simplify industrial setups, the 9825 effortlessly pairs across your entire transducer portfolio—including single-axis load cells, fluid pressure sensors, and static reaction torque transducers. It serves as an economic, space-saving panel-mounted display hub for UK manufacturing control cabinets, laboratory validation test stands, and automated factory weighing machines

Driven by a highly stable internal processing engine, the 9825 delivers an impressive internal resolution of 1,000,000 counts matched to a strict nonlinearity specification of < ±0.01% Full Scale (FS). As well as a ±999,999 count digital display that handles continuous tension and compression forces with equal accuracy. To accommodate fast structural testing cycles, the device can be user-toggled into a specialised Fast Mode to stream up to 1,200 readings per second, providing rapid peak and valley monitoring to capture sudden mechanical impact strikes without data latency. 

The Interface Model 9840 Intelligent Digital Indicator is a metrology-grade, single-channel instrument designed to serve as the definitive benchmark display for high-accuracy calibration testing rigs and laboratory verification. Engineered specifically to partner with premium force and torque standards, the 9840 delivers ultra-high data resolution and remarkable long-term stability. It is the premier choice across the UK for reference calibration laboratories, aerospace components auditing, national standards validation, and mobile testing systems where absolute certainty is non-negotiable.

At the core of the Model 9840 is an advanced 24-bit internal analogue-to-digital (A/D) converter engine that provides a rock-solid internal resolution of up to 1 part in 500,000. Operating on a bipolar data path, it effortlessly reads alternating tension and compression signals up to a full ±6 mV/V capacity spectrum. The indicator features automated plug-and-play profile pairing; it fully supports IEEE 1451.4 TEDS smart transducer protocols to instantly extract, scale, and map factory sensor parameters the moment a smart load cell is connected. To comfortably manage diverse laboratory configurations, the 9840 stores up to 25 independent, non-volatile internal calibration profiles, allowing technicians to manually scale non-TEDS sensors across multiple engineering units without losing baseline calibration factors or experiencing signal drift. 

TheInterface Model 9840-400 4-Channel Intelligent  Digital Indicator represents an elite, calibration-grade indicator engineered to manage four independent strain gauge force vectors concurrently. Designed as the multi-channel evolution of the industry-standard 9840 platform, this instrument brings remarkable internal resolution and reference stability to advanced testing environments. It is highly utilised across the UK for aerospace validation rigs, commercial metrology laboratories, and in-house safety calibration departments where multi-sensor comparison checks require absolute timing synchronicity.

The hardware architecture centres around two interactive 7-inch graphical touch screen displays, providing operators with sharp, simultaneous side-by-side data visualisation across all active ports. A premier mechanical advantage of this 4-channel layout is its capability to handle complex structural cross-compensation; it allows an engineer to monitor a primary vertical force, alongside a secondary redundant reference bridge while concurrently tracking background moments to fully control side-load errors. Fully compliant with IEEE 1451.4 TEDS plug-and-play standards, the 9840-400 reads and applies sensor calibration matrices automatically, dropping system configuration times to mere seconds while maintaining an exceptional non-linearity specification of < ±0.005% Full Scale.
