ABSTRACT:
An apparatus for measuring the torque of a force-transmitting operating shaft has a pair of measuring disks mounted on the shaft with each disk having a plurality of evenly distributed pulse generators. A sensor is associated with each measuring disk for transmitting energy bursts to the pulse generators. The pulse generators generate voltage pulses applied to receiving devices disposed behind the measuring disks, which pulses are compared in an electronic comparator. Each measuring disk has a plurality of pulse generators on two concentric graduated circles. The number of such pulse generators is different both from one graduated circle to the other graduated circle of the one measuring disk, and from one measuring disk to the other.
