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… WebThis technique is known as encoder and will depend on how the signal is decoded through the users drive, PLC or Controller. As a result, 10,000 pulses per turn can be generated from a 2,500 PPR quadrature encoder. …
