Sensor Technology has launched a new range of non-contact torque sensors based on a full four element strain gauge bridge design, complementing its existing non-contact sensors that use surface acoustic wave detection.

Designated the TorqSense SGR510/520 series, the new units have a 250% overrange reading capacity, allowing sudden spikes in torque to be measured and recorded accurately. The design also compensates for any extraneous forces, such as bending moments, inadvertently applied to the sensor, improves sensitivity and has a wide temperature tolerance. The measuring range of the SGR is 1Nm to 13000Nm, accurate to +/-0.1%, with a resolution to +/-0.01% of the transducer’s full scale.
