Abstract
A method and apparatus for non-contact testing of a rotating shaft includes first and second proximity sensors coupled to an automated shaft testing system. Output signals from the proximity sensors are compared to empirically determined threshold values to determine the presence or absence of a shaft coupling characteristic, the speed of the rotating shaft, and the direction of rotation of the shaft when the shaft is oriented proximally to the sensors.
