Rotational speed measurement with
Non-contact type Handheld Digital Tachometer
It can measure rotational speed simply by
affixing 12mm-square reflective mark (dedicated) on the
surface or edge of rotating shaft. It detects the
reflected light of a visible red light from the
reflective mark on the rotating body and displays the
rotational speed.
Measurement can be performed safely at a
distance ranging form 20 to 300 mm.
Measurement can be performed at the range
from 4 r/min to 50,000r/min. (Enable to measure at a
lower speed by affixing multiple reflective marks. 1 to
8 pieces.)
