Analog Rotary Torque Transducers with Square Drives – SGR515/SGR516

The SGR515/SGR516 Torqsense Rotary Strain Gauge Transducers (SGR series) utilise non-contact technology, eliminating the need for noisy slip rings. This makes them ideal for torque auditing applications.

Specifically designed for square shafts, these transducers offer a seamless fit, enhancing measurement accuracy and stability.

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.
