Centrifugal Force Tachometer
Overview
A centrifugal-force tachometer transducer contains masses that rotate with a shaft. Under a centrifugal force, masses are displaced proportionally to the speed. This displacement is sensed by one of the displacement-type elements (inductive, resistive, etc.) that produce an output electrical signal.
Centrifugal-force-tachometer transducer, w = angular speed, 1 = shaft,
2 and 3 = masses, 4 = displacement-sensitive element.
