Abstract
Détecteur de présence de métaux fondus. Il comprend un tronçon de conduit réfractaire pour métaux fondus traversé en son centre par un bras d'un transformateur d'intensité Lorsque le métal remplit ce tronçon de conduit, un courant secondaire de court-circuit s'établir dans le métal fondu, donnant naissance à un appel de courant au primaire que l'on détecte. Application à la coulée des métaux fondus.
