Abstract
The present disclosure is directed toward a method for measuring a true concentricity of a rotating shaft. The method includes simultaneously measuring, with diametrically opposed position sensors, opposite sides of the rotating shaft at an initial state to acquire a first measurement data and at a 180-degree rotation to acquire a second measurement data. The method further determines a rotational centerline and a shaft centerline based on the first and second measurement data, and calculates a concentricity error of the rotating shaft based on the determined rotational centerline and the shaft centerline.
