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.Electromagnetic sensor 10 comprising a primary winding 14, a secondary winding provided with a plurality of secondary coils 20 to 36 associated two by two in pairs, the coils of each pair being in phase opposition to form an elementary differential detector. The magnetic bar 12 modifies during its movement the magnetic coupling between said primary and secondary windings. According to the invention, the pairs 1 to n are electrically connected in series, and a weighting element is assigned to each pair to generate a weighted output signal. A processing circuit reports the weighted and unweighted voltages for reliable identification of the position of the bar 12. Application: PWR nuclear reactor.
