Abstract: The object is to ensure the absence of friction between a housing supporting a sensor and a mounting arranged to support a target, and the absence of load take-up resulting from the contact and lack of precision among mounting interfaces. This involves forming, in a mounting position, a clearance between the mounting and the housing and then releasing the target mounting in the operative position of the sensor. A cylindrical recess for freely receiving with a clearance the mounting supporting the reference element serving as a target and which is mountable on the shaft, is provided in the housing which supports the sensor and which is attachable to the stationary part. Removable locking elements provided between the mounting and the housing maintain the latter in an initial position when the locking elements are operative and, when inoperative, release the mounting mounted on the rotary shaft from the housing.

Abstract: A magnetic field generated by a primary winding (1) in which the current (i1) to be measured flows is balanced by a magnetic field of opposing direction generated by a secondary winding (2) in which a compensating current (i2) flows. The device includes a member (3) sensitive to the field resulting from the addition of the magnetic fields of opposing directions to regulate the compensating current (i2) in closed loop mode. According to the invention, the, sensitive member (3) is sensitive only to the direction of the resultant field and, in return, controls the reversal of the direction of circulation of the compensating current (i2) in the secondary winding (2). This sensitive member (3) can be formed by a Hall effect probe with bipolar output signal. The device is suitable for the measurement of a current inautomotive electronics.
