With its compact, robust and maintenance-free design, the Magtrol RT 100 Series Reaction Torque Sensor has many favorable features. Based on strain-gauge technology, the RT Sensor provides highly accurate signal transmission. The RT 100 Series Torque Sensor has been designed to perform static torque measurement and 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. Its design with a center through hole allows the pass through of a shaft, cables or pipes. Main field applications include actuator and valve testing, fastener testing, pump testing and automotive braking.
