Title (EN) MAGNETIC BREAKER SYSTEM FOR HORN
(FR) SYSTEME DE RUPTEUR MAGNETIQUE POUR AVERTISSEUR SONORE
Abstract:
(EN) The invention concerns a horn comprising a housing (1) wherein, the central part of the membrane (3) is integral with a solenoid plunger (7) arranged in the air gap of a coil (5). A Hall effect sensor (8) is maintained between a lower polar component (9) integral with the housing (1) and an upper polar component (10) opposite the solenoid plunger (7). An electronic circuit associated with the sensor (8) controls the powering of the coil (5). When the air gap (14) between the solenoid plunger (7) and the polar component (10) decreases, the magnetic flux through the sensor (8) increases, and for a detected flux value, the electronic circuit interrupts the current in the coil (5). The inventive breaker which operates without movement eliminates wear.
(FR) A l'intérieur du boîtier (1) de l'avertisseur, la partie centrale de la membrane (3) est solidaire d'un noyau plongeur (7) disposé dans l'entrefer d'une bobine (5). Un capteur à effet Hall (8) est maintenu entre une pièce polaire inférieure (9) solidaire du boîtier (1) et une pièce polaire supérieure (10) en regard du noyau plongeur (7). Un circuit électronique associé au capteur (8) commande l'alimentation de la bobine (5). Lorsque l'entrefer (14) entre le noyau (7) et la pièce polaire (10) se réduit, le flux magnétique à travers le capteur (8) augmente et, pour une valeur de flux détectée le circuit électronique coupe le courant dans la bobine (5). Le rupteur selon l'invention, sans mouvement, élimine l'usure.
