A New Electronic Device for Measuring Torque 650041

A new torquemeter applying digital technique has been developed for measuring transmitted torque. Digital indication of torque can be provided by converting into a number of pulses the force of a torsion bar derived from a transmitted torque. Since the twist of the rotating torsion bar is detected without any contacts such as slip rings, the torquemeter is especially accurate and adaptable for use with high speed engines. The instrument described here has been used successfully to measure torque of a gas turbine operating at 20, 000 rpm.
