Product brief introduction: special chemical explosion-proof thermocouple, thermal resistance as temperature measurement and control of the sensor and display instrument, to directly measure and control the production process of gas, liquid and vapor temperature.

I plant the production of special chemical explosion-proof thermocouple, thermal resistance products explosion-proof performance by the state promulgated the " electrical apparatus for explosive atmospheres ( GB3836) design and manufacturing standards, thermoelectric properties in line with the international IEC standards, and by the National Instruments explosion-proof safety supervision station test case, Certificate No.: GYB97172, GYB97173explosion environment ideal temperature sensor. According to the chemical fertilizer industry pipeline temperature measurement, and the explosion class is not higher than the class II B, spontaneous combustion temperature of not lower than T4(135 ℃) group and other1zone 2 zone ( indoor or outdoor ) in dangerous places.
