The glass-fiber bushing includes at least one tip-plate thermocouple having a platinum tube housing, a pair of thermocouple wires transversing the tube housing and terminating in a weld junction. The tube housing, thermocouple wires and the weld are attached directly to the tip-plate such that the thermocouple junction is formed directly at the tip-plate surface.
