  • Patent number: 4906349
    Abstract: A measuring probe for a measuring head to detect the oxygen activity of metal melts has a reference substance of known oxygen activity, which upon submersion into the metal melt is separated from the metal melt by means of a refractory solid electrolyte that conducts electrons reliably and conducts primarily oxygen at higher temperatures and which permits the measurement of the electromotive force between the reference substance and a bath contact which makes contact with the metal melt. The surface of the solid electrolyte is subjected to a surface cleaning treatment, primarily by means of etching.
