  • Thermocouples used for measuring temperatures
    Patent number: 3954507
    Abstract: This invention relates to thermocouple hot junction members which are used in immersion thermocouple assemblies employed for measuring the temperature of molten metal. At the temperatures involved, which are over 1200.degree.C and often in the region of 1800.degree.C and more, noble metals and alloys thereof have to be used to form a thermocouple conductor pair and up to now these have been united at the hot junction by a spot weld.In the hot junction of this invention the weld is replaced by a conductive refractory powder bridge so that the thermocouple conductor elements do not have to be joined. Each thermocouple conductor element is located in a leg of a quartz glass U-tube and the refractory powder bridge is located in the base of the U-tube so that opposed ends of the conductor elements are embedded in the powder which forms a thermocouple junction.
