How to Measure Reaction Torque?
A reaction torque sensor is a common torque measurement tool. The working principle is based on reaction force. When the torque on the rotating shaft changes. The elastic element inside the sensor will produce a corresponding deformation. This deformation will be converted and output through electrical signals. thereby achieving accurate measurement of torque.
Reaction torque sensor senses the change of torque by measuring the deformation of the elastic element. This deformation will cause the resistance value of the strain gauge to change. It is converted into a voltage or current signal through the bridge circuit. It can achieve accurate measurement of torque.
The reaction torque sensor indirectly obtains the torque value. It measures the torque reaction force at the fixed end (non-rotating end). Its core components include the Wheatstone bridge, composed of high-sensitivity strain gauges. When torque acts on the object to be measured, the fixed end of the sensor produces a slight deformation. The resistance value of the strain gauge changes accordingly. The bridge outputs a voltage signal proportional to the torque. The signal is converted into a digital signal after amplification and filtering. Some models integrate temperature compensation modules to eliminate environmental interference. Finally, achieve high-precision torque measurement.
What is a Reaction Torque Sensor?
A reaction torque sensor is a non-rotating torque sensor. It acts like a lever arm and a load cell without physically configuring the two.
