Characteristics & Usage:
The DYN-201 Rotary Torque Sensor is used to measure the rotational torque value. As the output frequency of the square wave signal or 4-20mA current signal, anti-interference ability, easy to use. Because the sensor is the transformer induction power supply, can work long term, widely used in motors, generators, reducer, diesel engine torque, speed and power detection.

Measuring principle:
Torque measurement
Using strain gauge electrical measurement technology, a strain bridge is formed on the elastic shaft, and the electrical signal of the elastic shaft is measured by supplying power to the strain bridge. After the strain signal is amplified, it undergoes voltage/frequency conversion to become a frequency signal proportional to the twist.

Speed measurement
The speed measurement is shown in the figure. The speed signal is converted into a pulse signal output through optical coupling and corresponding processing circuit. The rotating device outputs 60 pulses per revolution.
