  • Sensor for application in molten metals
    Patent number: 6514394
    Abstract: An electrochemical sensor to measure the activity of a metallic component in a molten metal, comprising the molten metal as the measuring electrode, a reference electrode containing the metallic component to be measured, separated from each other by a liquid ion-conducting halide comprising the metallic component to be measured and immobilized in a non-conducting porous support fabricated from a material inert or almost inert to the molten metal, the halide and the reference electrode material, and whereby the reference electrode further comprises an external connection comprising an electric wire held in an electric isolating material which is chemically inert or almost inert to the molten metal and the reference electrode material, characterized in that the sealing of the reference electrode which is adapted to be sealed is done by a high temperature cement and by the molten metal itself and by a gas tight sealing of the external connection above the melt, and the reference electrode is introduced by a melt
