  • Method and system for accuracy of speed and acceleration measurements on rotating machinery with a speed wheel
    Patent number: 7400993
    Abstract: A method and system for calculation of rotation dependent parameters in a system that senses shaft rotation of a toothed speed wheel. The method includes determining the passing edges of multiple gear teeth on a rotating speed wheel; calculating rotational speed of the rotating machine based on the passing edges of multiple gear teeth of the speed wheel; calculating a rotation independent tooth spacing correction factor for each gear tooth on the rotating wheel; and correcting the calculated rotational speed of the rotating machine using the tooth corrections.
