In a device for gauging relative rotational speed between the races of a bearing unit, a sensor is mounted to a fixed part and faces a rotating impulse ring. The sensor is incorporated within a detachable head (12) having releasable quick coupling means (13, 20), such as a clip, for mounting to a corresponding quick coupling seat (14), such as an appendix, rigid with the non-rotating race (15) of the bearing assembly. The appendix (14) is oriented in an axial or slightly inclined direction with respect to the axis of rotation. Mounting and removal of the head (12) is accomplished with a simple movement in said direction. <IMAGE> |
