Abstract
A device for measuring the rotational speed of a rotating object in which a tream of fluid from a back pressure sensor is directed at a chopper wheel attached to the rotating object. The output of the back pressure sensor varies as the chopper wheel rotates. The number of variations in pressure per unit time is directly proportional to the rotational speed of the rotating object.
