Abstract

Sonde de mesure de l'oxygène actif dans les masses métalliques en fusion. Selon l'invention, cette sonde comporte un corps de base (1) présentant un tronçon (5) partant de l'épaulement en direction opposée à celle de l'extrémité fichée dans le tube cartonné (14'), à la face frontale (7) duquel est agencée au moins la cellule électro-chimique (9) et en ce qu'un thermo-élément (11) conformé de façon connue est agencé dans une zone située entre l'épaulement (4) et la face frontale (7).Probe for measuring active oxygen in molten metal masses. According to the invention, this probe comprises a base body (1) having a section (5) starting from the shoulder in the direction opposite to that of the end inserted in the cardboard tube (14 ′), at the front face ( 7) of which at least the electro-chemical cell (9) is arranged and in that a thermo-element (11) conformed in a known manner is arranged in an area situated between the shoulder (4) and the front face (7 ).
