Abstract

PURPOSE:To detect torque correctly by a method wherein one of two signals having a phase difference corresponding to the torque value of the part to be detected is stepped-up in frequency and inversed in phase to seek AND together with the other signals for counting the pulses in a phase difference. CONSTITUTION:From the gears 3a and 3b at both ends of a tortion bar 2 and the sensors in the neiborhood thereof two signals having a phase difference corresponding to torque are taken out to make one of those into the signals S1' by converting frequency through a frequency communicator 6, while being made into the signals S1 by inverting phase through an inverter 7. Said both signals S1', S1 and other signal S2 are give to a logical circuit 8 to obtain AND for obtaining the signals S3. Said signals generate only for the time corresponding to the phase difference between the sensors 3a and 3b. These are counted through a counter 91 to indicate by an indication device 92. Thereby correct torque can be measured by a simple device requiring no strain gauge nor slip ring.
