摘要： A thermocouple used to measure a temperature of molten metal having a melting point of not more than 1200null C. is such constructed that a pair of alloy stock wires (5) and (6) capable of being used In a temperature region not exceeding 1200null C. is embedded in a protective pipe 3 made of ceramic. A measuring contact (2) formed by the extreme ends of a pair of alloy stock wires (5) and (6) connected to each other is secured to the protective pipe (3) by a filler (4) of an inorganic compound such as heat resistant ceramic powder or dehydrated condensation glass.

摘要： A thermocouple lance for measuring temperatures in molten metals has a protective sheath of multi-layered structure that makes it possible to improve the life expectancy of repetitive measuring devices. The thermocouple lance comprises a protective sheath with one closed end and one opened end wherein porous heat-resisting ceramic filler is compacted. Embedded in the filler is a pair of W-Re alloy wires dissimilar in their composition from each other. The protective sheath has the layered structure made from the cermet layers each having a molybdenum matrix and other layers of at least one selected from the class consisting of C, MgO, CaO, Al2O3 and ZrO2, both of which layers overlap each other in alternate layers. At least the outermost shell layer of the protective sheath is made of a cermet layer composed of any one of MonullZrN, MonullZrB2, MonullZrO2, MonullZrC and composite thereof.
