Abstract

Capteur de position à élément mobile modifiant le couplage inductif entre des bobines. Les bobines élémentaires primaire et secondaire sont couplées par paire et bobinées l'une sur l'autre pour accroître la concentration du champ magnétique. Le capteur peut être appliqué à un détecteur de position des barres d un réacteur nucleaire. Se référer à la figure unique.
