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