Design on torque check circuit using for gear test bed

On the basis of comprehensive analysis for the method of measuring torque, directed to the function of new type test-bed of gear-bed, the paper applys torque-sensor of phase angle difference and relevant circuits to it, and has solved the collecting work for torque information in the controlling system of test-bed of gear-bed. At the same time the paper has analyzed its working principle and output wave form.The testing result has proved that the system runs steadily,designs reasonably,has a great accuracy.
