What Are The Principal Factors That Affect The Life Of A Thermocouple?
Temperature: Thermocouple life decreases by about 50% when an increase of 50 °C occurs. Diameter: By doubling the diameter of the wire, the life increases by 2-3 times. Thermic cycling: When thermocouples are exposed to thermic cycling from room temperature to above 500°C, their life decreases by about 50% compared to a thermocouple used continuously at the same temperature. Protection: When thermocouples are covered by a protective sheath and placed into ceramic insulators, their life is considerably extended.
