ABSTRACT:
A rotational speed sensing device is disclosed which comprises a reference member adapted to be rotated at a reference speed, a rotational device coaxial with the reference member, the rotational device adapted to be rotated at a speed, a sensor associated with either the reference member or the rotational device and being rotated, the sensor for determining a speed differential between the reference member and the rotational device, and a controller electrically connected to the reference member and the sensor, the controller for receiving signals from the reference member and the sensor indicative of the reference speed and the speed differential, the controller for determining the speed of rotation of the rotational device based upon the difference between the reference speed and the speed differential.
