It works the same way a car tach works. It measures engine revolutions electrically from the coil/distributor or from a crankshaft sensor that is usually magnetic. On jet engines it is measured from the constant speed drive and is measured in percent of total power available rather than rpms.

How does magnetic tachometer work?
A magnetic tachometer works by using a rotating magnet on the shaft of the device being measured and a stationary magnetic pickup sensor. As the shaft rotates, the magnet passes by the sensor, inducing a voltage that is directly proportional to the speed of rotation. This voltage signal is then converted into a numerical value to provide the speed measurement.
How does optical tachometer works?
An optical tachometer works by using a light beam or sensor to detect the reflections off a rotating object. By measuring the frequency of the light reflections, the device can calculate the speed of the rotating object. The tachometer then provides a numerical readout of the rotational speed in revolutions per minute (RPM).
How does the Cessna plane work?
Cessna planes work by utilizing a piston engine to power the propeller, generating thrust to propel the aircraft forward. The wings create lift as the aircraft moves through the air, enabling it to take off, cruise, and land safely. Flight controls such as ailerons, elevators, and rudders are used by the pilot to maneuver the aircraft in the air.
