Multi-toxic gas monitor ОRT-02V (explosion-proof)

All the detectors of Ort series are supplied with the high-quality electric components of the leading foreign firms. The devices are highly competitive with the best foreign counterparts in regards to their technical characteristics while also having lower prices which means that they can compete with both foreign and domistic manufacturers.

Main distinctive feature that distinguishes them from the analogues present on the Russian market - high-reliability and long service life. It is achieved with the help of detecting elements (sensors) made by "Nemoto" (Japan) - a firm that takes leading positions in the gas and chemical branches of the industry and guaranties failure-free service for 8-10 years.

ORT-02B multi-toxic gas monitor is designed for continuous automatic measuring resulting in the light and sound alarm signals when the set limits of minimum explosible concentration of the combustible gaseous components are reached.

Application area:

Industrial facilities, boiler houses, community facilities, gas company, vehicle companies and other spaces where it’s possible for gas-and-air or steam-and-air atmospheric explosives to appear and accumulate. ORT-02B is a general-purpose industrial version of the stationary one-channel gas monitor with a convectional supply of the controlled media consisting of a remote measuring transducer and a signaling power unit.

All the ORT-02B devices pass primary calibration, each one has a full technical description and an instruction manual.

ОRT-02B gas monitor provides:

  • Digital indication of the explosion-proof components concentration, presented in % LEL(LFL);
  • Light and sound alarm if there’s an exceedance in the CO concentration in acc. with «Level 1» and «Level 2»;
  • Data-control alarm signals for the external devices using galvanically isolated relay outputs «Level 1» and «Level 2».
  • Code-digital indication and sound signal if there’re any breakdowns (measuring transducer/sensor breakdown, damaging of the communication line for measuring transducer and signaling power unit, etc.)

Main distinctive features:

  • Explosion-proof design variant with ex-marking of 1Ex ib d IIB T4 X Gb for the measuring transducer and [Ex ib Gb] IIB for the signaling power unit acc. to GOST 31610.0-2014;

  • Measuring transducer on the base of thermocaralytic sensors manufactured by «Nemoto Co.» (Japan);

  • A special “Control” mode for the on-the-spot fault checks of the light and sound signaling, gas analyzer relay outputs, correctness of the connection and operation of the external actuation devices.
