Blowing Thermocouple
Product Overview
Section titled “Product Overview”By blowing in nitrogen or other gases, harmful gases are sent out of the protection tube, thereby improving thermocouple service life. This product is an indispensable temperature-measurement device in 300,000-ton ammonia plants.
Applications
Section titled “Applications”- Temperature measurement in 300,000-ton ammonia plants.
- Temperature-measurement conditions where nitrogen or other gases are blown in to discharge harmful gases from the protection tube.
Product Advantages
Section titled “Product Advantages”- Nitrogen or other gases can be blown in to send harmful gases out of the protection tube.
- The blowing structure helps improve thermocouple service life.
- Protection level: IP65.
- Accuracy level: Class I or Class II.
Installation Method
Section titled “Installation Method”The structure diagram shows a thermocouple structure with a blowing-gas connection and a flange-connection structure. Confirm the blowing-gas connection, flange specification, and insertion length according to the site process connection.
