Computer personal explosion-proof series Orion MK PC

Explosion-proof personal computer Orion MK PC is designed for the implementation of automated workplaces with the ability to access information networks of an enterprise, as well as with video playback and visual display of information received via cable networks or the Internet. This personal computer allows both mobile posts and stationary guarding objects, tracking information of technological processes of the production cycle..

Application area for the automation of technological processes in the conditions of possible presence of an explosive environment at enterprises engaged in the extraction and processing of oil and gas products, as well as in chemical industries, mining and concentration complexes. It may be a post for collecting information in the security system and monitor the protected area..

An explosion-proof personal computer has an explosion-proof type “explosion proof enclosure “ d ”. Explosion protection marking PB Ex d I Mb X / 1Ex d IIС T6 Gb X according to GOST R IEC 60079-0-2011. The sign "X" in the marking means not to expose the light-transmitting part to mechanical stress..

Orion MK PC belong to explosion-proof electrical equipment of groups I, II, III according to GOST R IEC 60079-0-2011 and are intended for use in underground workings of mines, mines and their surface structures, as well as in explosive rooms, outdoor installations and dusty environments in accordance with the established marking of explosion protection, the requirements of TR TS 012/2011, GOST R IEC 60079-14-2011, other regulatory documents that govern the use of electrical equipment in hazardous areas and in areas that are hazardous for ignition of fuels she dust.

The Orion MK PC personal computer is designed to operate at an ambient temperature of minus 60 ° C to plus 50 ° C, a type of climatic version is UHL1 according to GOST 15150-69. Atmospheric pressure from 84 to 106.7 kPa. The degree of protection of the shell is IP67 according to GOST 14254.

Protection against electric shock in accordance with GOST class I. The metal case has a protective earth and working insulation from live parts.

Personal computer Orion MK PC are supplied with cable glands of various versions: 

  • for surface routing of the cable (designation index - К);
  • for routing the cablein pipe G1/2 (Т-1/2) or G3/4 (Т-3/4);
  • for connection of the armoured cable (B); 
  • for connection of the cable in metal hose RZTsH-15 mm or 20 mm (КМ10- КМ20).

Video cameras are completed with cable entries of the KV TU 3449-138-81888935-2016 series produced by “LLC Company SMD”. Connection thread for cable entries G1 / 2. Cable entries allow you to enter and output cables of circular cross section with a diameter of 6-12mm.


The Orion MK PC explosion-proof personal computer performs the role of an automated workstation (AWP) with input and output capabilities. When using SCADA-system, information collection, visual display, logical control, reporting and many other functions are provided. The main advantage of Orion MK PC is its ability to operate in places of possible presence of an explosive atmosphere, low temperatures, high humidity.

This explosion-proof equipment is an explosion-proof housing with an explosion-proof type of flameproof enclosure “d” and eliminates the occurrence of an explosion because the shell does not allow the escape of a spark or explosion beyond its chapels.

The data entry process is carried out by using a touch glass with a thickness of 6mm. An Orion MK PC explosion-proof computer is made of low carbon steel with subsequent painting or stainless steel. The case has the form of a rectangle with electrical devices installed in the inner space. Touch glass is glued on the inner contour of the front side over the monitor. The monitor is installed inside the shell and is fixed with the help of brackets. The internal space of the case is filled with a compound, which allows for increased protection against the penetration of moisture and the output of the spark discharge. The heating plate is also installed inside on a special plate that allows to uniformly heat all the space inside the case, which ensures operation at extremely low temperatures down to -60. One of the thermostats is set to the lower and the second to the upper chapel in terms of temperature, ensuring a constant temperature, preventing overheating or freezing. A box is installed at the bottom where the power indicator and control buttons for setting the monitor screen parameters are mounted. The installed protective cover over the buttons protects against increased danger conditions. Orion MK PC assumes a fixed installation and with the possibility of moving around the production.
