A tachometer is an instrument that measures the working speed of an engine, typically in revolutions per minute RPM. It is commonly used in cars, boats, planes, and other vehicles. Most tachometer gauges have either an analog dial or digital LCD or LED screen display. 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.
