The working principle and characteristics of explosion-proof thermocouple _ instrument

by:JVTIA     2020-10-29
Explosion-proof thermocouple flame-proof principle is to use the clearance, design has enough strength of the junction box, and other components, all will produce a spark, arc and dangerous parts are sealed in the junction box cavity temperature, when the explosion cavity, can remove from heat and cooling by joint clearance, made after the explosion flame temperature and not reach outside the cavity, flame-proof thereby. Explosion-proof thermocouple characteristics 1. Compression spring type thermal components, ant-vibration performance is good. 2. High measuring accuracy; 3. Without compensation conductor, saves the cost; 4. Imported film resistance element, reliable, stable performance.
