Abstract
L'invention concerne un capteur perfectionné de positon, du type à tube cylindrique et aimants. Les aimants peuvent se déplacer le long d'un ou plusieurs tubes, de maniere à aimanter à saturation les tronçons des tubes qu'ils recouvrent. Cette aimantation est détectée par un fil conducteur passant dans les tubes. La longueur utile de ces tubes peut être ajustée par la réalisation d'encoches dans les extrémités de ces tubes, afin de régler la pente électrique du capteur. Domaine d'application : capteurs de position pour automobiles.
