Name: Explosion-Proof Thermistor
Description:
Industrial explosion-proof thermal resistors are used as sensors for temperature measurement and control, paired with display instruments to directly measure and control the temperature of gases, liquids, and steam in the production process.
Our factory's explosion-proof thermocouples and resistance temperature detectors for chemical use are designed and manufactured in accordance with the national "Explosion-proof Electrical Equipment for Explosive Environments" standard. Their thermoelectric properties comply with the international IEC standards and have passed the testing by the National Explosion-Proof Safety Supervision Station for Instruments and Meters.
Explosion-proof thermocouples and resistance thermometers have similar structures, principles, and assembly methods. The main difference lies in the explosion-proof product's junction box (housing), which is made of high-strength aluminum alloy die casting and features ample internal space, wall thickness, and mechanical strength. The rubber sealing ring's thermal stability meets national explosion-proof standards. Therefore, when an explosive mixture inside the junction box explodes, the internal pressure will not damage the box, and the resulting heat energy will not spread outward – causing further explosion. As long as users strictly adhere to the product's usage instructions, reliable explosion-proof performance can be achieved.
Features
Spring-loaded thermosensitive element, excellent vibration resistance.
High measurement accuracy
No compensation wire required, cost-saving.
Imported thin-film resistor elements, reliable and stable performance.
Working Principle
Explosion-proof thermistors utilize the gap-type explosion-proof principle. They are designed with components, such as junction boxes, that have sufficient strength. All parts that can generate sparks, arcs, or dangerous temperatures are sealed within the junction box cavity. In the event of an explosion inside the cavity, the fire can be extinguished and cooled through the gaps in the mating surfaces, preventing the flame and temperature from spreading outside the cavity, thereby achieving explosion-proofing.
