ELECTRODYNAMIC POSITION TRANSDUCER

An electrodynamic position transducer (1) comprises: a rigid, hollow casing (2, 4) in which a membrane (5) is clamped which, together with a portion of the casing (2, 4), defines at least one chamber (6, 7) of variable volume; a coil (14) comprising at least one conductive track (14.1-14.6) formed on a support (16); an interaction element (13; 13') adapted to interact magnetically with the coil (14) as a result of a movement of the membrane (5), in such a way that the inductance of the coil (14) may be varied depending on the relative position of the movable element with respect to the coil (14); and a circuit (17) coupled to the coil (14) and adapted to provide electrical signals of which a parameter may be varied depending on the inductance of the coil (14). A hole or recess (18) is formed in the support (16) of the coil (14), which hole or recess is configured to receive the interaction element in such a way that one end (13a; 13.1a, 13.2a) of the interaction element (13; 13') may be positioned flush with or beyond a turn (T) of the coil (14).
