Explosion-proof thermal casing for installation of thermal imaging devices (thermal imagers) Orion MK TVR

Orion MK TVR is a thermal casing for installation in the internal space of a thermal imager and is designed for contactless measurement of the temperature distribution on the surface of the measured object and image transmission via cable networks, the Internet to the operator's post in the presence of an explosive atmosphere, as well as in the presence of aggressive media. Orion MK TVR allows you to shoot in any weather conditions, including at night.

The field of application is to ensure protection, safety and control over technological processes of explosive and aggressive industries in oil, oil refining, petrochemical, gas and other complex technological industries, including in mines and mines.

The Orion MK TVR thermo-casing has an explosion-proof type “explosion-proof casing“ 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 "X" mark in the marking means not to expose the light-transmitting part to mechanical stress.

Explosion-proof thermal casing Orion MK TVR refers 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 explosion protection marking, the requirements of TR CU 012/2011, GOST R IEC 60079-14-2011 and other regulatory documents that regulate the use of electrical equipment in hazardous areas and in areas hazardous to the ignition of combustible dust.

Explosion-proof thermohousing Orion MK TVR are designed for operation at ambient temperatures from minus 60 ° C to plus 50 ° C, type of climatic modification UHL1 in accordance with GOST 15150-69. Atmospheric pressure from 84 to 106.7 kPa.The degree of protection of the shell is IP67 in accordance with GOST 14254.

Protection against electric shock in accordance with GOST 12.2.007.0-75: class III / class I.The metal case has protective grounding and working insulation from live parts. With a supply voltage of 220V AC, protection class I, with a supply voltage up to 24V DC or AC - protection class III.

The Orion MK TVR thermohousing is produced in versions that differ in the case material, overall dimensions, and supply voltage.

Orion MK TVR are supplied with two cable glands of different designs:

• for open laying of the attached cable (index in the designation - K );
• for laying the attached cable in the pipe G1 / 2 ( T-1/2 ) or G3 / 4 ( T-3/4 );
• for connecting armored cable ( B);
• for connecting a cable in a metal hose RZTsKh-10mm, 12mm, 15mm or 20mm ( KM10-KM20).

The Orion MK TVR thermohousing is completed with cable glands of the KV TU 3449-138-81888935-2016 series produced by LLC Company SMD.Connecting thread of cable glands G1 / 2.Cable glands allow you to enter and exit cables with a circular cross-section with a diameter of 6-12 mm.

Design

Orion MK TVR is used in conditions of possible exposure to aggressive media of both natural and artificial nature.This equipment is explosion-proof and allows you to completely exclude the occurrence of an explosion when hazardous gases, vapors, liquids leak in the production cycle, as well as to be used in a security system, early detection of fire, failure in technological processes (release of critical thermal energy from the set values), overheating of equipment and heat carriers ...

Orion MK TVR is a thermal casing in which a thermal imaging camera (thermal imager) is placed, taking into account the fact 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 casing allows the thermal casing to be operated at high humidity, low temperatures, as well as at increased mechanical stress.The inner space of the camcorder is equipped with heating in case of a drop in temperature, the optimal operating mode is established.

The Orion MK TVR thermohousing is an explosion-proof housing with a type of explosion-proof explosion-proof enclosure “d”.The explosion-proof thermohousing is made of low-carbon steel; corrosion-resistant steel; aluminum alloy.The body is a hollow cylinder with welded flanges for attaching the covers.The back cover of the casing is fixed to the casing with six screws and has two female-threaded fittings on the outside for installing cable glands, and on the opposite side, which is installed inside the casing, a power board with thermostats is mounted.With the help of thermostats, it is ensured that the internal space of the thermal imager is warmed up.With a "cold start", power is supplied to the thermal imager after warming up the inner space of the video camera.When the temperature reaches above + 55 ° C, the thermal imager is powered off.To exclude the ingress of moisture, dust, rubber seals are used at the attachment points of the removable body parts.A visor mounted on top of the body is also an element that limits adverse environmental conditions.

Orion MK TVR is supplied with a bracket for mounting on a horizontal or vertical plane, as well as a console bracket for mounting on a pipe.
