WRN-740 Chemical Special Explosion-proof Thermocouple

 

As the temperature measure and control sensor,

chemical special explosion-proof thermocouple is

completed with display instrument to measure and

control the gas, liquid and vapor temperature in production.

 

Our products are manufactured and designed according

to "explosive environment, explosion-proof electrical

equipment (GB3836) standard. Thermoelectric performance

is line with international IEC standard and tested by the

National Safety Supervision Station. The qualified NO. is

GYB97172、GYB97173. It is the ideal temperature

sensor in explosive environment.

 

for the fertilizer industry, its explosive level is not

higher than the Ⅱ B-class, self-ignition temperature

is not less than T4 (135 ℃).
