The HRDT is now replaced by the Axial TQ. https://interfaceforce.co.uk/sensors-for-your-force-and-torque-and-pressure-measurement-applications/axial-tq-wireless-torque-transducer

The Interface Model BSC4A and BSC4D 4-Channel Bridge Amplifiers are legacy, high-density analogue signal conditioners engineered to capture and scale metrics from multi-axis force sensors and multi-sensor weighing setups. Designed to fit narrow mechanical spaces, these compact amplifiers allowed engineers to process four independent strain gauge bridges simultaneously within a single hardware enclosure. They served as a trusted component for industrial robotics, structural material test rigs, and automotive testing applications across the UK where multiple forces required clear, real-time tracking.

The BSC4 is discontinued and has been replaced by the BSC6A

The Interface Model DFI-05L High Precision Digital Indicator is a metrology-grade, microprocessor-based instrument designed to provide exceptionally clear, high-resolution visual force telemetry from any standard strain gauge transducer. Engineered specifically for calibration workstations, product verification benches, and manufacturing quality control rooms, the DFI-05L delivers outstanding precision where standard industrial panel meters fall short.

The DFI-05-L has been replaced by the DFI-05-U Universal digital indicator and is no longer available . Please visit https://interfaceforce.co.uk/force-torque-and-pressure-measurement/dfi-05-u-universal-digital-indicator/ for more information The DFI-05-L is a panel mount digital indicator designed for use with load cells in either weighing, torque or force measurement applications. Its dual slope 16 bit ADC performs 10 conversions each second with a resolution of 1 part in 63,000 and a maximum sensitivity of 1V. Load cells can be wired in either 4 or 6 wire configuration and up to 4x 350R units can be connected to each indicator for platform or vessel weight displays. Standard features include Adjustable Filters, Automatic Zero Drift Compensation, Peak and Valley Detection, Display Filter, Last Digit Roundup, In-flight compensation and multiple point calibration with the Lineariser feature (maximum 10 points).

The Interface TR1 Rod End Reaction Torque Transducer is a legacy static sensor explicitly engineered to mount inline between structural rods, linkages, or tubes for non-rotary torque monitoring. Please note: The TR1 series has been discontinued. This data is maintained for legacy engineering reference and retrofitting assistance. Please contact our technical sales team to discuss modern, active replacement sensors offering direct mechanical compatibility and advanced output options.

The Interface Model DFI-02 6-Digit Digital Force Indicator is a legacy, high-accuracy desktop and mobile instrument engineered specifically to provide ultra-high resolution force and weight readings from strain gauge sensors. Widely integrated into mobile testing kits and laboratory desktop stands, the DFI-02 served as a trusted component for ISO-7500/1 and ISO 376 verification systems. Its compact portable housing, built-in tilt leg, and rugged carrying handle allowed metrology technicians to seamlessly transport high-precision calibration metrics straight to various testing fields. 

NO LONGER AVAILABLE - please see the 9840

Developed for Medical, Aerospace, Automotive, and Manufacturing industry needs, the WTS wireless sensor communication system provides a way to monitor forces where wires are difficult to manage or install. A load cell or torque transducer is attached to the WTS-AM transmitter, which uses an input of mV/V, 5V or 4-20mA and transmits a 2.4GHz digital output to the receiver. The receiver (WTS-BS) can be either a hand-held with 6 digit indicator or a USB / analogue device capable of logging data during the users tests.

• No cables! In some applications cable runs can be difficult
• Battery Power - Wireless, so mains power not required
• Long battery life: includes battery sleep / wake commands
• One hand-held display can be used with multiple sensors
