Abstract
A method assesses the rotational speed of a machine, and more particularly the rotational speed of a rotating equipment prime mover controlled by a governor. Such machines include turbo machinery and relate to a measurement device for measuring speed. The method measures a number of pulses during a measurement interval, determines a portion of a pulse pattern, determines an integration period, and calculates the rotational speed based on the portion of the pulse pattern.
