Product Details
Product Overview
Chemical specific explosion-proof thermocouples and thermal resistors are used as sensors and display instruments for temperature measurement and control, to directly measure and control the temperature of gases, liquids, and vapors in the production process.
The explosion-proof performance of the chemical special explosion-proof thermocouples and thermal resistance products produced by our factory is designed and manufactured in accordance with the national standard for explosion-proof electrical equipment for explosive environments (GB3836). The thermoelectric characteristics comply with international IEC standards and have been tested by the national instrument explosion-proof safety supervision station. The certificate numbers are GYB97172 and GYB97173, which are ideal temperature sensors for explosive environments. For pipeline temperature measurement in the fertilizer industry, with an explosion level not higher than Class II-B and a self ignition temperature not lower than T4 (135 ℃), it is a hazardous area in Zone 1 or Zone 2 (indoor or outdoor).
