    摘要: The contactless angular displacement and/or torque pickup is characterized in that it comprises two electrically insulating coaxial disks (7a, 7b) that can turn in relation to one another by an angle to be detected and that carry on their opposing faces conductive plane coils (8) in the shape of spirally wound sectors coiled alternately in both directions and whose mutual induction varies as a function of the relative angular position of the detection disks (7a, 7b). Also included is a rotary transformer (6a, 6b) to supply one of the detection disks (7a, 7b), a circuit (18) for supplying the primary (11a) of the rotary transformer and a circuit (17, 18) for processing the signal (S) collected on one of the detection disks (7a, 7b).
