ABSTRACT:
This disclosure relates to a system for measuring the instantaneous speed of an index point on a rotating part. The part may be a toothed gear or a wheel of an engine, and the index point may be an identifiable point on the part. The system comprises a sensor that is mounted adjacent the part, the sensor including two sensing elements that are spaced apart in the direction of movement of the point as the part rotates. As the point passes the sensor, it causes a first pulse to be produced by one element and then a second pulse to be produced by the other element. The system further includes circuitry that responds to the two time-spaced pulses and produces an indication of the time interval between the two pulses. This time interval is a function of the speed of the point which in turn is proportional to the rate of rotation of the part. In the instance where the part is attached to an engine flywheel, the time interval is also an inverse function of engine RPM.
