Abstract

Circuit d'équipement ayant un détecteur de l'état de boucle à cellule de Hall dans lequel pour obvier au fait que le rapport du champ magnétique de commutation Bc au champ de relâchement Br dépasse celui des courants admissibles pour signaler l'état de boucle, on injecte ou une force contre-électromotrice eo ou un champ magnétique Bo de sens opposé à celui du champ pilotant la cellule de Hall. Le champ Bo peut être injecte soit directement soit par l'intermédiaire d'un courant Io , éventuellement injecté dans l'enroulement de tonalités. Utilisable dans les centraux téléphoniques.
