Why should explosion-proof detectors be installed with explosion-proof housing?

Explosion-proof detector is used in explosion-proof places. It is a gas detection device installed in an explosive and dangerous environment. It converts the concentration of flammable gas in the field into digital signal and transmits it to the gas alarm controller located in the safety zone to monitor the concentration of flammable gas in the field. Most of the purposes are used in places where explosive gases such as flammable pipes are dense.
The explosion-proof double detector adds infrared function to this function, which can detect the movement of the human body and prevent people who are unintentional from entering the defense zone to do illegal things, causing losses to individuals and society. Explosion-proof double detectors with concentration detection comply with GB 3836.1 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", GB 3836.2 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion-proof Type "d"" and GB 15322.1 "Combustible gas detectors Part 1: Measuring range 0 to 100% LEL point flammable gas detectors" and other standards. On the basis of the explosion-proof double detector, other monitoring systems can be added as an explosion-proof three-detector or an explosion-proof four-detector.
Why explosion-proof double detectors must use explosion-proof housing
1. Explosion-proof double detector is used in explosive gas environment, so it must be explosion-proof;
2. The explosion-proof double detector has a high temperature inside, so there must be isolation measures;
3. Explosion-proof double detectors usually use explosion-proof explosion-proof measures. The basic requirement is that when an internal explosion occurs, it will not ignite and detonate the external combustible gas. Therefore, its outer casing must be able to withstand and absorb the explosive energy and achieve a safe discharge of the explosion pressure.
