Abstract

Sonde de type différentiel pour le controle non destructif de produits sidérurgiques basée sur le principe des courants parasites ou de la résonance électromagnétique, qui ne nécessite pour son fonctionnement qu'un seul enroulement, la fonction du second enroulement étant remplie au moyen d'un ordinateur.Differential type probe for non-destructive testing of steel products based on the principle of parasitic currents or electromagnetic resonance, which requires only one winding for its operation, the function of the second winding being fulfilled by means of a computer .
