Product Details
Explosion proof armored thermocouple
OverviewWR □ - □ 4 □ Explosion proof industrial thermocouple is designed and manufactured in accordance with the mandatory national explosion-proof standards GB3836.1-2000 and GB3836.2-2000, and has been inspected and approved by the national level instrument explosion-proof safety supervision and inspection station, obtaining an explosion-proof certificate. It is suitable for use in explosive gas mixture environments under specified conditions.
Explosion proof grade: dIIBT1~6
Explosion proof certificate: GYB13.1608X
Execution standard: GB3836.1-2000 General requirements for electrical equipment used in explosive gas environments
GB3836.2-2000 Electrical equipment for explosive gas environments - Explosion proof type "d"
JB5518 "Technical Conditions for Industrial Thermocouples and Thermal Barrier Explosion"
WR □ - □ 4 □ Explosion proof thermocouple is a temperature sensor composed of an explosion-proof junction box, a thermoelectric electrode, and an external protective tube with threaded or flanged mounting and fixing devices. It can be widely used for temperature measurement in the range of -40~1100 ℃ in the dIIBT1~6 temperature group area with explosive gas hazards.
