Abstract

L'invention concerne une installation combinant un dispositif de contrôle 14 par ultrasons et un dispositif de contrôle 15 par courants parasites. Le premier fonctionne suivant le principe du transformateur électrodynamique et les bobines des deux dispositifs sont centrées et disposées l'une par rapport à l'autre de façon que les parties explorées de la pièce aient un axe principal commun. Un appareil de commande 16 raccordé à l'installation assure l'enclenchement et le déclenchement automatique rapide et alterné des deux dispositifs de contrôle 14 et 15 en fonction du niveau d'excitation de la bobine du transformateur. Un appareil approprié reçoit et traite les valeurs mesurées par les deux dispositifs.
