Abstract
Dispositif détecteur de positions particulières d'une pièce mobile, par exemple d'une pièce en rotation rapide, munie d'éléments débordants magnétiquement doux passant à tour de rôle à proximité du dispositif detecteur qui comporte un circuit magnétique fixe excitateur du cristal à effet Hall. Le circuit magnétique excitateur est constitué par un aimant permanent unique dont une face polaire, orientée vers la pièce mobile, est munie de deux pièces polaires symétriques magnétiquement douces entre lesquelles est ménagé un entrefer étroit dans lequel est disposé le cristal à effet Hall utilisé. Application au repérage très précis des positions angulaires particulières du vilebrequin d'un moteur thermique à combustion interne.
