Abstract

PURPOSE:To obtain correct torque value with a simple device by taking out the digital signals having a phase difference according to the torque value of the part to be tested from two portions and providing an analong signals corresponding to the phase difference. CONSTITUTION:A torsion bar 2 is provided with gears 3a and 3b on both sides thereof while the sensors 4a and 4b are arranged in the naborhood thereof. When a detector 1 rotates, the sensors 4a and 4b produce digital signal S1 and S2 having a phase difference corresponding to the torque. These are compared in respect of phase through a phase comparison circuit 6 to be made into the outputs Q1 and Q2, which in turn are changed into an analogue signal according to the difference between both signals by a D/A converter 7 and put into a filter 8, the output thereof being given to a torque indicator device 12 through a variable resistor 10 and an amplifier 11 to enable the reading of the torque. Thereby correct torque can be measured with a simple device requiring no strain gauge nor a slip ring.
