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 ℃).
