Optical rev counter
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes from Greek τάχος (táchos "speed") and μέτρον (métron "meas… WebDec 28, 2008 · Would it be easier to integrate signal from an optical rev counter ? I have no RPM gauge for my 4-107 and I'm thinking to rig an optical job in front of crank-pulley with reflective strips on the pulley. Model shops do hand RPM meters for about 20 quid ... and others, some of the classier models have connector leads to feed gauges. 27 Dec 2008 #11
