Machine designers have been presented with a significant new technology for measuring power in drive shafts and other rotating machine elements, following the launch of the RWT310/320 series of TorqSense Rotary Torque sensors suppliers by developers Sensor Technology Ltd.

Unlike traditional slip ring transducers, the RWT units make use of a simple non-contact measurement technique of a radio frequency (RF) couple for power and signal communication. This means that the units are mechanically straightforward and as such they stand to completely redefine the expectations of machine builders and control engineers, who to date have had to put considerable time and expense into obtaining the accurate torque readings essential for accurate machine control and production monitoring......
