The blowing type armored thermocouple is a key temperature measuring instrument for the annual production of 300000 tons of synthetic ammonia complete set equipment. Its structural principle is to form a certain gas path between the temperature sensing element of the armored thermocouple and the outer protective tube. Inert gas greater than 1.03x105 Pa is introduced into the gas path to eliminate or reduce the infiltration of reducing gas into the thermocouple under high temperature and high pressure conditions, thereby extending the service life of the armored thermocouple.
