Analog Rotary Torque Transducers – SGR510/SGR511/SGR512

Our TorqSense rotary strain gauge transducers utilise non-contact technology, eliminating the need for noisy slip rings. They are ideal for torque measurement, testing, feedback, and control of drive mechanisms, particularly in process control applications that require analogue outputs.

The SGR series transducers employ advanced strain gauge signal conditioning techniques to deliver high-bandwidth analog outputs, available as fixed voltage or current signals for seamless integration with analog instrumentation. Three output channels are provided, with channel assignments depending on the specific model, offering a versatile and cost-effective torque measurement solution with excellent overrange and overload capabilities.
