In the production of oil, gas, chemical and other industries, inflammable, explosive, corrosive chemical gas, steam and liquid is very common. In order to achieve industrial production automation, workers need a temperature sensor to automatically measure and control the process, while the use of aluminum alloy explosion-proof junction box can no longer meet the safety requirements for flame-proof .

  Serial anti-explosion changeable-diameter thermal couple and resistor adopt full stainless steel junction box (flat junction box) and could be applied in ExdⅡBT4～5, ExdⅡCT1～6 which demands the highest level of protection---IP65, where corrosion and explosive atmosphere is around.

1) temperature and tolerance

2) Junction box: stainless steel flat explosion-proof junction box, optional small stainless steel junction box (P2) or large stainless steel junction box (P1).

3) protection tube: variable diameter overall drilling, optional material.

4) Process connection: threaded connection, specifications are M27 × 2, M33 × 2, NPT1 / 2 ", NPT3 / 4", NPT1 ", etc., can also be used flange connection.

5) temperature measurement components: single, double armored components φ3, φ4, φ5, φ6, φ8 optional.

6) can be equipped with integrated temperature transmitter, temperature change optional intelligent or ordinary type.
