Series 2300 and 2500 strain-gauge reaction torque sensors measure brake torque, bearing friction, and pump or motor torque. They feature high torsional stiffness, flange mounting, and are available in fullscale capacities from 5000 to 500,000 lb-in. (0.56 to 56.5 kN-m). They are supplied with a shunt calibration resistor.
