Abstract

a. L'invention concerne un dispositif pour déterminer la position et le nombre de tours d'un arbre en rotation, comportant un disque denté et un capteur muni d'une bobine, les dents du disque modifiant la perméabilité magnétique d'un circuit à tension constante. b. Ce dispositif est caractérisé en ce que le disque denté présente au moins un élément de référence provoquant une modification supplémentaire de perméabilité magnétique lorsqu'il passe devant le capteur. c. L'invention est applicable, notamment, aux vilebrequins de moteurs à combustion interne.
