New torque sensor to revolutionise machine control

Sensor Technology will be launching their new E400 Torqsense Rotary Torque Sensors at the Mtec Exhibition at NEC, 11-12 February: The E400 units utilise a SAW based non-contact measurement technique

Sensor Technology will be launching their new E400 Torqsense Rotary Torque Sensors at the Mtec Exhibition.

The E400 units utilise a non-contact measurement technique, so reduce the previously difficult task of accurate real-time torque monitoring to the simple task of literally mounting the transducer close to the machine drive shaft under investigation.

As such they stand to completely redefine the expectation of machine builders and control engineers.

They feature integral electronics with digital and analogue outputs for torque, speed and power and are directly compatible with PC Interfaces such as serial and USB, being user programmable for analogue signal levels.

Other innovative features include built-in peak torque sampling, storage and torque averaging.

They can operate from a wide range of supply voltage.

To achieve the non-contact operation that makes the Torqsense transducer range unique, SAW (Surface Acoustic Wave) devices are used as frequency dependent strain gauges to measure the change in resonant frequency caused by strain experienced in the drive shaft.

This measurement is directly related to the torque and opens up new horizons for advancing all manner of machine control.
