Abstract

L'invention concerne un capteur de régime inductif pour un turbo-compresseur, comprenant un noyau métallique guidant un champ magnétique généré par un aimant, et une bobine enroulée au moins partiellement autour du noyau, ledit capteur de régime inductif étant disposé dans la zone d'entrée d'air d'un carter de compresseur du turbo-compresseur. Le but de l'invention est de proposer un capteur de régime inductif de turbo-compresseur, qui n'engendre pas de perturbations aérodynamiques dans l'entrée d'air du compresseur, qui soit facile et économique à monter sur le carter de compresseur et qui délivre cependant un signal de régime de grande qualité. A cet effet, le noyau du capteur de régime inductif présente l'entrée d'air au moins partiellement sur sa face externe, le champ magnétique étant ainsi guidé vers la bobine.
