Abstract
A device for detecting one or more parameters of a rotary member angular displacement, includes: and instrumented roller bearing ( ) provided with a non-rotating part including a non-rotating ring ( ) and a sensor block ( ), a rotating part including a rotating ring ( ) and a coding ring ( ) mounted opposite the sensor block ( ) and at least a row of rolling elements ( ); and elements for processing signals transmitted by the sensor block. The sensor block ( ) comprises at least two sensing elements ( ) 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 elements a redundant information on the parameter of angular displacement.
