Abstract

L'invention concerne un dispositif de détection du niveau de la surface des crasses d'un appareil de décrassage d'un bain métallique. Ledit dispositif comporte deux électrodes en forme de tige à la périphéne de l'extrémité avant d'un tube aspirant, qui dépasse ladite extrémité d'une distance appropriée, et un dispositif destiné à détecter des variations de la résistance électrique entre lesdites élcctrodes. Application au décrassage de bains de métal ou autres matières en fusion.
