High-temperature, irradiation-resistant thermocouple, coaxial thermocouple, and related methods
Patent
·
OSTI ID:1986655
A coaxial thermocouple includes a wire, an insulation layer surrounding the wire, a sheath surrounding the insulation layer, and an electrical junction formed between the wire and the sheath and at one longitudinal end of the coaxial thermocouple, the electrical junction including a swaged end with an outer diameter of the sheath reducing in diameter along a longitudinal length of the coaxial thermocouple until the sheath contacts the wire within the insulation layer. The wire includes a first material and the sheath includes a second material where the first material includes one of molybdenum (Mo) or niobium (Nb) and the second material includes the other of molybdenum (Mo) or niobium (Nb).
