Abstract
Explosive atmospheres can be caused by gases, vapors, mist, dust, lint, or fibers of flammable substances. If there is a sufficient quantity of the substance mixed with air, the imminence of an explosion depends on the probability and efficiency of the ignition source. The type of pressurized enclosure protection consists of separating the potentially explosive atmosphere from the ignition source by maintaining an overpressure inside the enclosure using a protective gas. The use of the equipment in an enclosure with a risk of an explosive atmosphere is accepted after going through the certification and testing process. Testing is carried out by the standards for explosion-protected equipment with pressurized enclosure protection. The main conclusion of the work is that the use of a new oxygen analyzer allows ten times higher value resolutions.
