Abstract (en)
[origin: WO0179860A1] The invention concerns a device for detecting one or more parameters of a rotary member angular displacement, comprising: an instrumented roller bearing (1) provided with a non-rotating part including a non-rotating ring (2) and a sensor block (8), a rotating part including a rotating ring (2) and a coding ring (15) mounted opposite the sensor block (8) and at least a row of rolling elements (4); and means for processing signals transmitted by the sensor block. The sensor block (8) comprises at least two sensing elements (9, 10) co-operating with the single coding ring, signals transmitted independently by each sensing element corresponding to the same parameter of angular displacement, so as to supply to the processing means a redundant information on said parameter of angular displacement.
