 The basic principle of torque measurement
Torque measurement: The strain gauge electrical measurement technology is used to form a strain bridge on the elastic shaft. The electrical signal of the elastic shaft torsion can be measured by supplying power to the strain bridge. After the strain signal is amplified, it is subjected to pressure / frequency conversion.

Rotational speed measurement: The magnetoelectric code disk is used for measurement. Each magnetoelectric code disk has 60-180 (optional) teeth. The shaft drives the magnetoelectric code disk to produce 60-180 (optional) pulses per revolution, high speed Or in the medium speed sampling, the frequency measurement method can be used, and in the low speed sampling, the accurate rotation speed can be measured by the period measurement method. Speed ​​measurement can be up to 15000rpm. The accuracy of this sensor can reach ± ​​0.1% ~ ± 0.5% (F · S). Because the sensor output is a frequency signal, it can be sent directly to a computer for data processing without AD conversion.

The speed measurement method of this sensor adopts built-in speed measurement, the user needs to indicate whether to monitor the speed signal when ordering.

Product features:

1. The square wave amplitude of the signal output waveform can be selected from 5V / 12V / 15V / 24V.
2. You can enter the working state within 5 minutes of starting up without preheating process.
3. High detection accuracy, good stability and strong anti-interference.
4. The forward and reverse torque can be measured continuously without repeated zero adjustment.
5. Small size, light weight, easy to install.
6. The sensor can be used independently from the secondary instrument. As long as the power supply of ± 15V (200mA) is provided according to the pin number of the socket, the frequency signal of equal square wave or pulse wave with impedance proportional to torque can be output.
