Traditional mechanical tachometers had an analog needle to indicate engine RPM. Some modern electronic instruments also use an analog needle rather than a digital display. The operation of a mechanical tachometer is similar to that of a mechanical speedometer. A flexible cable with a rotating shaft connects a moving part in the engine or transmission to the gauge. Inside the instrument, the rotating shaft controls the position of a needle to indicate the engine speed. The heart of a mechanical tachometer is an eddy current sensor that contains a movable magnet driven by the rotating input shaft. The spinning magnet in the sensor imparts a force on the indicator needle proportional to the engine speed, while a spring counteracts the sensor force.
