Processing Method of the Signal of JCZ Torque speed sensor

In order to measure the torque and rotational speed, changes the torque and the rotational speed signal into electric signal of two sine signal through the torque speed probe of Model JCZ. Reconanends the phase-different detecting circuit, analyzes each node signal waveform and the output signal waveform of the circuit, proposes the processing method of the signal with the same precision to be measured based on P89LPC932. This method effectively eliminates the influence of the rotational speed to measure the torque, improves the precision of measuring. This method has already applied to the testing system of gearbox loaded, and makes the anticipated result. Practical application shows that The measurement result of this method is accurate, steady, reliable.
