Summary:
A tachometer is a measuring device with the purpose of measuring the speed of a circular plate or disk, or sometimes of a shaft. The word comes from the Greek words meaning speed (tachos) and measure (metron).
A tachometer is typically used in measurement of engine speed in an automotive engine, but was originally used to describe centrifugal force. The German engineer Dietrich Uhlhorn is believed to be the inventor of the tachometer. His interest was in measuring the spee…

A tachometer is a measuring device with the purpose of measuring the speed of a circular plate or disk, or sometimes of a shaft. The word comes from the Greek words meaning speed (tachos) and measure (metron).
A tachometer is typically used in measurement of engine speed in an automotive engine, but was originally used to describe centrifugal force. The German engineer Dietrich Uhlhorn is believed to be the inventor of the tachometer. His interest was in measuring the speed of machines. The use of the tachometer in measuring the speed of locomotives has been common since about 1940, and it is also used in measurements of light rail axle speeds.
The early tachometers were entirely mechanical, but it is interesting to note that the modern day version relies entirely on electronic measurements to register as part of a computerized system. Find more info at http://www.tachometerworld.info
For instance, the tachometer, although described in revolutions per minute (RPM
