Abstract
An electromagnetic accelerometer including a stationary stator element (12) associated with a movable polar element (14) securable to an external member (2), the stationary stator element (12) and the movable polar element (14) forming a magnetic circuit and defining between them at least two gaps (51), a magnet (5) helping to create magnetic field lines in the magnetic circuit, a coil (6) and a mechanism for energizing the coil for controlling the displacement of the movable polar element (14) through electromagnetic induction phenomena. The electromagnetic accelerometer further includes an adjustment polar element (15) for placing the movable polar element (14) in an adjusted position with respect to that of the stationary stator element (12), by deviating the magnetic field lines.
