ABSTRACT:
A rugged quick-response thermocouple for use in measuring the temperature of a gas flow includes two wires formed of different metals and electrically joined at an exposed junction. A ceramic sheath substantially surrounds the two wires except near the junction. The sheath is surrounded by a stainless steel tube. The junction is positioned adjacent an end of the ceramic sheath. In one embodiment the wires are coated with an insulator and the insulator is positioned against the flat end of the sheath. The exposed junction resists damage from gas flows and from corrosive compounds in the gas mixture.
