摘要

An instrumented bearing (10), comprising a fixed outer ring (16) and a rotating inner ring (20), is equipped with an encoder (30), a sensor assembly (34) comprising a read head (36) positioned opposite and at a reading distance from the encoder (30), and from a leakage current collector (44), capable of coming into sliding contact with an annular contact (46) capable of being secured directly or indirectly with the inner ring (20). The encoder (30) and the read head (36) are positioned axially between the outer ring (16) and the leakage current collector (44). A conductive electrical connection (54) between the leakage current collector (44) and the fixed outer ring (16) also constitutes a magnetic shielding of ferromagnetic material, extending from the outer ring (16) to the current collector. leakage (44) by surrounding the encoder (30) and the read head (36). (Fig. 1)
