Title (EN) SENSOR HEAD FOR EDDY CURRENT SENSORS
(FR) TETE DE CONTROLE POUR CAPTEURS A COURANTS DE FOUCAULT
Abstract:
(EN) The invention relates to a sensor head for eddy current sensors used in non-destructive testing, said head having high wear resistance. The sensor head comprises a substrate having at least one electromagnetic field emitting/receiving element and an outer face that can move on the surface of a structure to be inspected, said outer face being covered with a metal foil.
(FR) Une tête de contrôle pour capteurs à courants de Foucault utilisés dans les contrôles non destructifs, qui présente une forte robustesse à l'usure. La tête de contrôle comprend un substrat ayant au moins un élément émetteur/récepteur de champ électromagnétique et une face externe apte à se déplacer sur la surface d'une structure à inspecter, et est telle que la face externe est recouverte d'un clinquant métallique.
