A tachogenerator is is an electric generator that generates a voltage that is accurately proportional to the speed of the shaft. Generating a voltage proportional to the speed is an inherent characteristic of all generators, but tachogenerators are specifically designed to provide an accurate signal over a specified range of load currents and operating temperatures. The output signal from a tachometer generator(tachogenerator) is often used to provide feedback to improve the regulation of an electric motor speed control.
A tachometer is an instrument that measures and displays rotational speed. An electric tachometer combines the tachogenerator with a voltmeter that has the dial marked to show speed rather than voltage.

A tachogenerator is a device that generates an electrical signal proportional to the speed of rotation of a shaft, while a tachometer is an instrument that measures the speed of rotation of a shaft. In essence, a tachogenerator produces the signal that a tachometer measures.
The tachometer in my car measures the engine's revolutions per minute. The mechanic adjusted the tachometer to ensure the engine was running smoothly. The driver glanced at the tachometer to check if the engine was being pushed too hard.
A tachogenerator is a type of electromechanical device that generates an electrical signal proportional to the rotational speed of a shaft or motor. It typically consists of a rotor attached to the rotating shaft and a stator with coils that produce the electrical signal as the rotor spins. The generated signal can be used to measure and monitor the speed of the rotating machinery.
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
The inventor is unknown for a tachometer. However, the first documented use of a tachometer device was by the German engineer Dietrich Uhlhorn in 1817. He is credited with its first use, but not necessary as being its inventor.
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
