Sensor Technology TorqSense SGR 510/520 torque sensors 

TorqSense SGR 510/520 torque sensors cover capacities from 0.2 to 1 Nm, making the full range 0.2 to 13,000 Nm. The bigger units are designed for use in machine tools, production and processing plant, heavy duty pumps and similar large-scale installations.

Based on a full four-element strain gauge bridge design, the SGR sensors have the ability to measure and record sudden spikes in torque load.

The sensor measures the torque 4000 times per second and uses high performance signal conditioning to provide a high bandwidth monitoring solution. This is further enhanced by 250% overrange and 400% overload capabilities, elimination of side and end load errors and real-time temperature compensation.

The non-contact signal transmission means the sensor exerts no load on the shaft it is monitoring, while maintenance-heavy slip rings have been designed out.

Three analog output channels on the 511 mean the SGR can measure real-time speed and power alongside the torque monitoring. A third output is dedicated to self-diagnostics and/or status functions. An Ethernet gateway module can also be fitted to the unit.

As well as analog outputs, TorqSense SGR 520/521 is also fitted with digital outputs for interfacing with instrumentation and laptops. Options include RS232, CANbus and USB. A digital input is provided so that the 520/521 can be set up directly from a PC running specialist configuration software such as Sensor Technology’s TorqView or LabView.
