The Interface AxialTQ Wireless Rotary Torque Transducer System represents the next generation of high-performance wireless rotary torque measurement. Developed through direct collaboration and input from over 30 global end-users, this highly adaptable system redefines the rotary transducer category by focusing on absolute accuracy, user customization, and streamlined field setup. It is widely specified across the UK for demanding test rig validation loops, automotive powertrain dynamometers, high-speed electric motor efficiency evaluation, and industrial gearbox test beds where traditional slip-ring friction cannot be tolerated.

At the absolute core of the Interface AxialTQ system lie the high-fidelity rotor sensing element and on-board telemetry electronics. Operating on a completely non-contact wireless transmission structure, the device continuously monitors across a wide axial gap. This structural freedom provides a bearing less design that entirely eliminates the rotational wear and maintenance downtime common to legacy torque cells. The Axial TQ is offered in 8 torque capacities and 5 rotor sizes with flexible capability of stator and output module built in.

The Interface Flange Mount Rotary Torque Transducers represent an elite class of dynamic torque transmitters engineered for space-constrained automotive dynamometers, aerospace test cells, powertrain validation loops, and precision rotating machinery. Unlike standard long-body shaft transducers, a flange-to-flange architectural layout delivers exceptional mechanical advantages, including high torsional stiffness and an ultra-short axial length. This compact geometry allows engine builders and test facility managers to drop a dynamic measurement node straight into high-RPM drive lines without altering system alignment or inducing critical driveline vibrations.

This premium product family incorporates advanced non-contact / contactless digital telemetry technology to broadcast precise torque measurements through a bearingless or floating architecture. This design completely eliminates the frictional wear, maintenance overhead, and electrical brush bounce common to legacy slip-ring designs, ensuring long-term data integrity across continuous operational schedules.

The T31, T32, T33 and T34 series are all contactless rotary devices offering torque measurement in capacities from just 1Nm to 500Nm at up to 2,000rpm.
