Abstract:Aiming at the fault appeared during the use of armored thermocouple, the insulation resistance and performance of the thermocouple were analyzed, and experimental tests were carried out in harsh environments such as high temperature and oil contamination. The study indicated that the welding quality of thermocouple measuring end and the size of insulation resistance were main influence factors on the precision and service life of armored thermocouple. It was pointed out that in order to ensure the temperature measurement precision and the service life of thermocouple, the insulation resistance should be tested strictly before purchasing and using.
