Abstract

A device for detecting the displacement of a mobile metallic mass intended to be momentarily placed in the immediate vicinity of said mass, characterized in that it comprises means for emitting magnetic flux suitable for reigning in a detection zone intended to be crossed by at least a part of said mass, a non-constant magnetic flux, electromagnetic receptor means of said flux, and means for detecting the variation of currents induced in said receptor media by said flux, normally receiving any of said receptor media, in the absence of said metallic mass, an amount of said flow different from that received by the other receiving means, the set of said receiving means forming with said emitting means an open magnetic circuit destined to be modified by the presence of said metallic mass in said detection zone, said receiving means being arranged and electrically connected in such a way that That the currents induced in said receiving means are opposed in the same circuit that includes said means detecting the variation of the induced currents.
