Operating Principle

The sensor works on the principle of reluctance. Whenever the motion detection sensor detects a ferromagnetic target, a signal in the form of a pulse is given to the microprocessor (in the evaluation unit). The microprocessor evaluates the time between consecutive pulses and converts it into ppm (objects per minute). When the speed becomes less than the programmed 'underspeed-A' value, underspeed-A relay changes the state. When the system rotates at a constant speed, the time gap between two consecutive pulses remains constant. Now, if an object (and hence pulse) is missed, this time gap increases. This is sensed by the microprocessor and it operates the missing object relay. The relay outrput contacts can in turn be used for signaling or controlling. Flashing LED in the preamplifier indicates that the moving target is within the sensing range and facilitates target-to-detector distance setting.
