ABSTRACT:
An electronic sensor for detecting motion and the rate of motion, particularly rotative movement, utilizes digital control apparatus wherein pulses are transmitted to a digital counter at a rate proportional to the rate of rotation of the member being sensed, and the pulses are compared with a time reference signal to produce a control sequence for comparing the pulses to predetermined set point values wherein an alarm or control signal is produced if the rate of rotation of the member sensed deviates between predetermined set points. The pulses being sensed are produced by an infrared light passing through a light shutter mounted upon the rotating member being sensed wherein the rate of pulsation of the light passing through the shutter is directly related to the rate of shutter rotation, and the pulses are sensed by electronic means producing a control signal.
