Digital Rotary Torque Sensors with Square Drives & External Electronics – SGR545/SGR546

Our TorqSense rotary strain gauge transducers use non contact technology, eliminating the need for noisy slip rings.

Specifically designed for square shafts, the SGG545/SGR546 transducers offer a seamless fit, enhancing measurement accuracy and stability in applications with non-cylindrical shafts.

The addition of the external electronics module enhances the versatility for applications such as torque measurement, testing, feedback control of drive mechanisms, and process control, ensuring dependable performance even in challenging conditions.

The SGR series transducers use modern strain gauge signal conditioning techniques to provide a high bandwidth, low cost torque measuring solution with high overrange and overload capabilities, and a wide range of digital outputs.
