Abstract
PURPOSE: To directly measure the concentration of sulfur in molten metal simply and quickly, by measuring the electromotive force through the use of solid electrolyte.
CONSTITUTION: The solid electrolyte 1 having high temperature stability withstanding high temperature of molten metal and having good sulfur ion conductivity such as Y2O2S, Eu2O2S, Gd2O2S, Tb2O2S, and Ce2O2S, oxysulfide monomer or mixed sintered body of a plurality of rare earth elements, is fixed to the tip of the alumina protective tube 4, and the sulfur compound 2 for standard electrode is provided in contact with the solid electrolyte internally, and it is connected to the high impedance potentiometer 12 connected to the external electrode molybdenum rod 5 via the molybdenum rod 3 and the lead wire 10. Thus, when the detection terminal is immersed in molten metal containing sulfur, the electromotive force produced across the solid electrolyte 1 is measured at the high impedance potentiometer 12 and the concentration of sulfur can be detected from the measured electromotive force.
