Explosion-proof PCs are an automation tool for the implementation of various process control systems (APCS) at industrial enterprises engaged in the extraction and processing of oil and gas products, as well as in the chemical industry, fuel distribution storage, chemical and pharmaceutical industry, mining industry, civil construction in hazardous environments, printing, textiles, etc.Based on a PC and additional equipment, including the ORION series (PC, cameras, router-router, thermal imager, switch, fire detectors, sirens, etc.)etc.), it is possible to organize operator posts to track technological processes, emergencies, protect facilities, account for various vehicles, etc.Hardware and software integration makes it possible to directly interact with video surveillance and equipment of alarm systems, SCAD, obtaining the following advantages: creating a configuration, transferring information to equipment, polling devices and obtaining the status of technical means, managing object devices, displaying an object plan with visual observation of the state of the incident, promptly transferring the assessment to the relevant services, displaying the image on a PC from nearby cameras.
PCs, depending on the configuration, are used in places where the presence of an explosive gas mixture is unlikely (Zone 2) or where there is a possibility of an explosive gas mixture (Zone 1) .PCs can be used in various industrial sectors, including in the mining complex for the extraction of minerals by underground or open pit.The environment may contain explosive mixtures of gases, vapors with air, dust categories IIB+H2, IIC and IIIC including IIA, IIB, IIIA, IIIB.
PCs differ in configuration, both internal and external (see.tab. 2), housing material, material of the light-transmitting part, method of receiving and transmitting data, type of installation, dimensions, configuration.Explosion protection marking depending on the configuration is given in Table 1.Specific performance is specified when ordering.
PCs are made from aluminum alloy, stainless steel, or mild steel.In the manufacture of PC for mines and mines, light-alloy materials (aluminum alloy) are not used.The material of the light-transmitting part is monolithic polycarbonate or tempered glass.
