ABSTRACT:
An RTD assembly is welded directly to the heat receiving surface of a heat exchanger and shields the resistance element from the combustion gasses and thermally isolates the resistance element from the sheath of a sheathed cable which electrically connects the RTD to remotely located associated circuitry. The resistance element is maintained in direct contact with the heat receiving surface of the exchanger to provide an accurate measurement of the temperature of that surface.
