Abstract:
A device for detecting one or more angular displacement parameters pertaining to a rotary member, comprising: an instrumented rolling bearing (1) of the type provided with a non-rotating part comprising a non-rotating ring (3) and a sensor block (8) mounted on one face of the non-rotating ring, with a rotating part comprising a rotating ring (2) and an encoder ring (15) mounted facing the sensor block and with at least one row of rolling bodies (4) arranged between two raceways of the non-rotating and rotating rings; and means for processing signals emitted by the sensor block, wherein the single sensor block comprises at least two detection elements (9, 10) collaborating with the single encoder ring, signals emitted independently by each detection element corresponding to the same angular-displacement parameter, so as to provide the processing means with redundant information about said angular displacement parameter.
