   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.

   Apr 2, 2023 · A tachometer is an instrument that is used to measure the speed of an object, mostly a motor. It is majorly used to measure the rotational speed of the shaft or disc when the machine is in motion. If the shaft is moving and when you touch the tachometer in conjunction with the shaft, the tachometer will show you the actual motor speed in RPM.

   Apr 28, 2023 · A tachometer measures the rotational speed (rpm) of an engine or other rotating machinery. A speedometer measures the speed of a vehicle in terms of its linear velocity (mph or km/h). It indicates how fast the engine’s crankshaft is spinning. It indicates how fast the vehicle is moving in relation to the ground.

   Tachometer, device for indicating the angular (rotary) speed of a rotating shaft. The term is usually restricted to mechanical or electrical instruments that indicate instantaneous values of speed in revolutions per minute, rather than devices that count the number of revolutions in a measured time.
