Abstract
A device for gauging relative rotational movement and/or displacement between the races (10, 11) of a bearing comprises a pulse generator (13) activated by the rotating race (11) and coupled to a non-rotating sensor (12). The pulse generator consists of a coding wheel and the sensor consists of an optical encoder. The coding wheel (13) comprises a disk of reflecting material on which a plurality of non-reflecting zones or apertures is provided.
