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.
What does a tachometer measure?
A tachometer refers to any device that produces a signal proportional to the speed of rotation of a joint. There are many different types of tachometers, some based on measuring the frequency of, or the time between, pulses generated by the rotating shaft.
How does a car tachometer work?
It works by bringing a freely spinning wheel in contact with a rotating shaft or disc. The shaft drives the wheel to generate the pulses. These pulses are then read by a tachometer and measured in revolution per minute. It can also calculate the linear speed and distance.
