ABSTRACT:
A thermocouple, for measuring the temperature of flat strip moving horizontally through a furnace, extends vertically into the furnace and can move vertically within a fixed guide assembly. The ceramic insulated thermocouple element, inside an outer thermocouple member, can move within the outer thermocouple member, in response to the urging of a spring, and has a contact pad composed of a metal with a melting point such that a layer of molten metal forms on the contact pad from frictional heat from the moving strip. In a second embodiment, for measuring vertically moving strip, with the thermocouple assembly horizontally positioned, the thermocouple assembly includes a second spring to urge the thermocouple assembly horizontally into the furnace against the moving strip.
