ABSTRACT:
An improved thermocouple and method for making the thermocouple and installing same on the fireside of heat exchanger tubes or the like for monitoring surface temperature which includes a thermocouple assembly made from mineral oxide insulated metal sheathed thermocouple wires where a pair of thermocouple wires or conductors extend through a metal sheath in spaced apart and insulated relation from each other and from the sheath and are connected together at an end to define a hot junction member adapted to be mounted in engagement with the surface being measured, which hot junction is defined by a disk or bar-shaped member extending from the end of the sheated conductor assembly beyond the insulation and sheath but not in contact with the sheath. Installation on a heat exchanger tube includes welding the sheath to the tube which pressurizes the hot junction against the temperature measured surface and defines a heat energy path that bypasses the hot junction.
