Digital Rotary Torque Sensor with Incremental Angle Encoder – SGR523

Our TorqSense rotary strain gauge transducers use non contact technology, eliminating the need for noisy slip rings. They are suitable for torque measuring, testing, feedback and control of drive mechanisms and process control applications.

The SGR523 torque transducer now includes an external incremental encoder for precise angle measurement, making it particularly versatile for applications such as mechanical test stands, bolt or bottle cap tightening test stands, and other machinery.

With the SGR523, torque versus angle plots can be analysed to gain a deeper understanding of mechanical losses. Knowing the exact shaft angle at which torque peaks or dips occur is crucial for test stand engineers, providing insights into rotational stiction that may occur at specific shaft positions. In process control applications, monitoring the expected torque values at specific shaft angles helps detect any potential issues that need to be addressed to prevent production wastage.

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.
