A torque sensor is a transducer that converts a torsional mechanial input into an electrical output signal. Torque transducer can be classified into two categories, reaction torque sensor (static torque sensor) and rotary torque sensor (dynamic torque sensor) depending on the torque to be measured. Reaction torque sensor can measure non-rotating torque or torque with small rotating angle while rotary torque transducer is able to measure both rotating torque and non-rotating torque.
A digital load cell amplifier / transmitter can be matched can be used with the torque sensor supports RS485 communication interface and amplified signal output DC 4-20mA, 0-5V, 0-10V which is proportional to the measured value. The amplifier is integrated with high accuracy 24-bit ADC, 80 times/s sampling speed making it suitable for both static measurement and dynamic measurement.
