Working Principle Contact Tachometry A light beam from a diode is reflected by a rotating mirror located inside the probe head. A light sensitive cell detects the frequency of the signal of the beam which is proportional to the rotation speed. Optical Tachometry A light beam emitted from the diode the probe is reflected by a reflective tape placed on the rotating disk. A light sensitive cell detects the frequency of the signal of the beam which is proportional to the rotation speed.
