Abstract

L'invention concerne un dispositif de détection pour mesurer par induction le déplacement de contacts de commutation électriques dans des appareils de commutation électromagnétiques. Ce dispositif comprend au moins une bobine d'excitation (2) polarisée par une tension alternative, et au moins une bobine de mesure (4) couplée par induction à cette dernière, ainsi qu'un noyau mobile (8), pénétrant au moins en partie dans les deux bobines (2, 4) et servant à détecter un signal électrique produit en fonction du déplacement accompli par les contacts de commutation. Ce dispositif de détection présente une bobine de compensation (6) comportant un noyau (10) se déplaçant en fonction du déplacement des contacts de commutation et pénétrant au moins en partie dans la bobine de compensation (6).
