Sensor Technology is to unveil the Torqsense RWT330/340 series of non-contact measurement sensors for space-critical applications at M-Tec 2009.
The RWT330/340 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 RWT330/340 series of non-contact measurement sensors for space-critical applications.
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 slip rings, or high-inertia 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.
The company's larger sensors are used in many applications at the heavy duty end of industry, and the smaller ones are used in applications such as fine chemical dosing and lab-based research.
At both ends of this spectrum are applications where splitting the sensing head from the control electronics is desirable.
It may be a space constraint or it may be a matter of protecting the electronics from harsh environmental conditions such as heat, damp, noise, vibration or EMC.
