Sensor Technology is to unveil the Torqsense RWT330/340 series at the M-Tec Exhibition.
The RWT330/340 is designed for use in applications where space is limited.
It provides non-contact measurement of torque, speed, power and position of rotating shafts, such as machine drives, drive shafts for pumps, fans, mixers and so on, and in the critical axes of test rigs.
Torqsense uses tiny piezo-ceramic combs fixed to the transducer's shaft that distort in proportion to the instantaneous torque level.
These create data signals that are transmitted via a non-contact radio frequency coupling rather than by conventional but clumsy slip rings, or high enertia rotary transformers.
Because piezo technology requires so little power, this is also supplied via the RF coupling.
This data signal is transmitted to the control unit, from which it can be read on an alpha-numeric display or transferred to a PC for storage and analysis using the Torqview software programme.
