Intrinsically Safe Thermocouple

In chemical factories, production sites often contain various flammable and explosive gases, and steam. Using ordinary thermocouples is extremely unsafe as it can easily trigger environmental gas explosions. Therefore, explosion-proof thermocouples must be used as temperature sensors in such situations. Our company's explosion-proof thermocouple products are suitable for use in areas with explosive gas hazards within the dⅡCT6 temperature class range.

Explosion-proof thermocoupleWorking Principle:

If a closed loop is composed of homogeneous conductors (thermocouples) made of two different components, and there is a temperature gradient between the ends, then an electric current will flow through the loop, and there will be a thermoelectric potential between the two ends (as shown in the following diagram).

Explosion-proof thermocouplePrinciple:

Utilizing the gap-type explosion-proof principle, we design components such as junction boxes with sufficient strength. All parts that generate sparks, arcs, and dangerous temperatures are sealed within the junction box. In the event of an explosion inside the cavity, the fire can be extinguished and cooled through the gaps at the mating surfaces.Fire and temperature from the explosion do not spread to the outside of the cavity.

Explosion-proof thermocoupleFeatures:

Designed in accordance with the latest explosion-proof regulations GB3836 that conform to international IEC standards.

Utilizes a two-chamber explosion-proof structure; easy to replace temperature sensing elements; safe and reliable operation.

Explosion-proof marking dⅡCT6, suitable for temperature measurement in environments with explosive gases below II C classification and above ignition temperature T6.
