Abstract

Dispositif de mesure (10) comportant un circuit magnétique comprenant un premier élément d’armature (11) et un deuxième élément d’armature (12), positionnés de part et d’autre d’un axe X et fabriqués avec au moins un matériau ferromagnétique ; un aimant (13) situé entre lesdits éléments d’armature de sorte qu’un premier pôle (13a) de l’aimant est positionné du côté du premier élément d’armature (11), et qu’un deuxième pôle (13b) de l’aimant est positionné du côté du deuxième élément d’armature (12) ; une tige (14) agencée pour être solidaire d’une cible et insérée entre lesdits éléments d’armature pour coulisser selon l’axe X, la tige présentant une section variable selon sa longueur, de sorte qu’un flux magnétique dans le circuit magnétique dépend d’une position linéaire de la tige selon l’axe X ; au moins un capteur (15) agencé pour mesurer le flux magnétique, et donc la position linéaire de la tige (14), et donc de la position linéaire de la cible.
