Heat-insulated enclosures explosion-proof for the installation of thermal imaging devices (thermal imagers) Orion MK TVR

Orion MK TVR is a heat-insulated enclosures for installation into the inner space of a thermal imager and is designed for contactless measurement of temperature distribution on the surface of the object being measured and transferring the image over cable networks, the Internet to the operator’s post in the presence of an explosive atmosphere, and in the presence of corrosive media. Orion MK TVR allows you to shoot in all weather conditions including at night.

A scope in ensuring protection, safety and control of technological processes of explosive and aggressive productions oil, oil processing, petrochemical, gas and in other difficult and technological productions, including in mines and mines.

Heat-insulated enclosures Orion MK TVR has explosion protection rated to "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.

The Orion MK TVR explosion-proof heat-insulated enclosures is an explosion-proof electrical equipment of groups I, II, III according to GOST R IEC 60079-0-2011 and is intended for use in underground mines of mines and their ground 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 CU 012/2011, GOST R IEC 60079-14-2011 other regulatory documents that govern the use of electrical equipment in hazardous areas and in areas of igniter flammable dust.

Heat-insulated enclosures explosion-proof Orion MK TVR designed for operation at ambient temperatures from minus 60 ° C to plus 50 ° C, type of climatic design 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 according to GOST class III / class I. The metal case has a protective earth and working insulation from current-carrying parts. At a supply voltage of 220V AC, protection class I, at a supply voltage up to 24V DC or AC, protection class III.

Heat-insulated enclosures Orion MK TVR are produced in versions that differ in the case material, dimensions, supply voltage.

Orion MK TVR 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 .


Orion MK TBP is used in conditions of possible exposure to aggressive media of both natural and artificial nature. This equipment is explosion-proof to completely eliminate the occurrence of an explosion in case of leakage of dangerous gases, vapors, liquids in the production cycle, as well as use in a security system, early detection of fire, failure in technological processes (release of critical thermal energy from the specified values), overheating of equipment and heat carriers.

Orion MK TVR is a heat-insulated enclosures in which a thermal imaging camera (thermal imager) is placed, taking into account that ordinary borosilicate glass does not transmit thermal radiation, germanium glass is used. This glass provides infrared transmission and a high refractive index. The degree of protection of the shell allows you to operate a thermocouple at high humidity, low temperatures, as well as with increased mechanical loads. The internal space of the video camera is equipped with heating in cases of low temperatures, the optimum operation mode is set.
