Abstract

L'invention concerne un dispositif de capteur de courant de Foucault comprenant une partie bobine et un boîtier. La partie bobine comprend : une bobine d'excitation permettant de générer un premier champ magnétique ; et une bobine de détection permettant de détecter un signal électrique correspondant à un second champ magnétique généré par un courant de Foucault induit dans une structure cible par un premier champ magnétique, et à un champ magnétique synthétisé du premier champ magnétique. Le boîtier entoure la partie bobine et bloque cette dernière de l'extérieur tout en logeant cette dernière à l'intérieur du boîtier. Une partie magnétique, logée et fixée à l'intérieur du boîtier afin de fixer le boîtier et la partie bobine à la structure cible par une force magnétique, peut en outre être comprise. Un capteur de courant de Foucault de résistance à la traction d'un câble permettant de fournir un changement de contrainte en fonction de la résistance à la traction est situé sur la surface d'au moins un coin, ajusté par pression entre le câble et une tête d'ancrage de telle sorte qu'une perméabilité magnétique de ce dernier change en fonction de la contrainte du câble. Une partie de surveillance de résistance à la traction émet un signal d'excitation au capteur de courant de Foucault et calcule des informations sur la résistance à la traction du câble à l'aide du signal électrique détecté par le capteur de courant de Foucault. Si la résistance à la traction calculée descend sous une valeur seuil admissible, une alerte de danger est émise automatiquement. Dans un véhicule d'essai, une puissance d'entraînement est fournie à la partie surveillance de résistance à la traction d'une manière à induction magnétique, et des informations d'intensité de traction de câble mesurées par le capteur de courant de Foucault peuvent être collectées à partir de la partie surveillance de résistance à la traction.
