Company: Sensor Technology Ltd
Description: Manufacturers of TORQSENSE Transducers, the world's first low cost non-contact rotary torque
transducers designed for OEM applications.
Rotary torque measurement has always been difficult and expensive. The patented method uses a surface acoustic
wave device as a frequency dependent strain gauge and measures the change in resonant frequency caused by the
applied strain in the shaft. The signal is transmitted via an RF couple from the rotating shaft to a fixed pick-up.
By using a frequency-based device, the signal bandwidth is increased, and the problem of electronic interference
common with analogue signals is eliminated.
The torque sensors are designed to operate direct from a PLC or a PC. They require minimum length of shaft,
have low inertia, no physical contact between shaft and housing, wide bandwidth, high resolution and accuracy
resolution to better than one part in a million, and excellent noise immunity. The technology lends itself to design
of OEM transducers for specific customer applications.
Applications include automotive, manufacturing machines, condition monitoring where knowledge of torque is critical,
torque control of tightening procedures, and monitoring of viscosity during mixing where consistency is required.
