Product Description
With its compact and maintenance-free design, the RT 200 Reaction Torque Sensor from Magtrol brings many signicicant advantages to torque measurement applications. Based on strain-gauge technology, the RT 200 Reaction Torque Sensor provides highly accurate torque measurement. The RT 200 Reaction Torque Sensor has been designed to perform high precision static torque measurement with small dynamic rotation (and limited angle) in both the clockwise and counterclockwise directions. The sensor measures small-reaction torque values using shaft connections in-line with the component under test. Main field applications include actuator and valve testing, and fastener testing on medical devices.

Torque Calibration Laboratory
Rossens, Switzerland – ISO 17025 Accredited
Magtrol torque calibration laboratory consists of 3 lever calibration benches covering a range from 0.1 Nm to 5,000 Nm as well as a motorized geared bench covering a range 1,000 Nm to 50,000 Nm. The measurement uncertainties of calibration rigs are at 0.01% level of the rated torque range. The laboratory was designed and built to meet the metrological requirements, avoiding floor vibration and temperature fluctuations that could disturb the measurements.
