The mechanical method of measurement is indispensable in the case when only the end of the rotation shaft is available for measurement, or the rotation speed is extremely low.
To measure optically, it is necessary to stick a piece of reflective tape (foil) on the radial surface of the pulley, turn on the device and direct the emitter towards the object.
Mechanical measurement requires the transmission of a rotational force to the instrument shaft.
To do this, the tachometer comes complete with two front friction nozzles (rubber, protruding and reverse cone) - if it is possible to rest against the end of the rotating shaft.
Also, the device is equipped with a nozzle - a friction wheel, for measuring the linear speed relative to the surface of the rotating shaft (pulley, wheel). Wheel diameter 32 mm.
