Abstract

Capteur électromagnétique 10 comprenant un enroulement primaire 14, un enroulement secondaire muni d'une pluralité de bobines secondaires 20 à 36 associées deux à deux en couples, les bobines de chaque couple étant en opposition de phase pour former un détecteur différentiel élémentaire. La barre 12 magnétique modifie au cours de son déplacement le couplage magnétique entre lesdits enroulements primaire et secondaire. Selon l'invention, les couples 1 à n sont branchés électriquement en série, et un élément de pondération est affecté à chaque couple pour engendrer un signal de sortie pondéré. Un circuit de traitement fait le rapport des tensions pondérée et non pondérée pour le repérage fiable de la position de la barre 12. Application : réacteur nucléaire PWR.
