A photo-reflective sensor in panel mount tachometer is a type of tachometer that uses a specialized sensor to measure the speed of a rotating object. The photo-reflective sensor works by reflecting light off the spinning object onto a light-sensitive surface. The light-sensitive surface measures the reflected light to calculate the speed of the rotating object. This type of tachometer is typically used to measure the speed of motors, engines, and other rotating objects.

Used in industrial applications to monitor the performance of motors.
Employs the principle of photorefictive scanning using a light source, photo sensor & reflector. The visible light beam through photo-probe is to be aligned with the reflector (applied on rotating shaft /disc /drive) at 4″ to 12″ distance. The receiver senses the reflected light beam each time target passes through light beam. Time interval between reflected light which is proportional to speed is processed / computed & RPM is displayed on panel meter.
Photoprobe consists of threaded 22mm x 70mm long brass chrome plated probe with locknuts. It houses light source of bright intensity with a photo receiver. A quality optic lens is mounted inside to focus the light on reflector and to send back reflected light from reflector. 3 wire cable has been provided to transmit signal. Photo sensor has to be mounted perpendicular to reflector at a distance of 4” to 12”.
