Blowing thermocouple
The structural principle of the blowing type thermocouple is to install the temperature sensing element of the armored thermocouple and the outer protective tube
A certain gas path is formed between them, in which a certain pressure of inert gas is introduced to eliminate or
Reduce the infiltration of reducing gas into thermocouples under high temperature and high pressure conditions, and add trace amounts of tantalum element
In addition, it increases the suction characteristics of the blowing type thermocouple, thereby extending the use of armored thermocouples

Service life. The key temperature sensor used for the complete set of ammonia synthesis equipment.
