RT 100 Series Reaction Torque Sensors

 
SpecificationsData Sheet

With its compact and maintenance-free design, the RT100 Series Reaction Torque Sensor from Magtrol brings many appealing advantages to torque measurement applications. Based on strain-gauge technology, the RT Sensor provides highly accurate signal transmission. The RT100 Series Torque Meter has been designed to perform static torque measurement and small dynamic rotation (with limited angle) in both clockwise and counterclockwise direction with high precision. The sensor measures small-reaction torque levels using flange-to-flange connections in-line with the component under test. Main field applications include actuator and valve testing, fastener testing and automotive braking.
