       First in Russia, we have developed and set in lot production a model range of infrared multispectrum noise-protected flame detectors for running in usual or explosion-dangerous environment. "NABAT" flame detectors are designed for detecting flames and fire focuses, and for preventing spontaneous outing the flames of gas burners and torches. They can be used in explosion-suppression systems.
In our NABAT flame detectors instead of the conventional principle of flame identification (by low frequency oscillations of radiation), we use the principle of spectral selection that provides them a high sensitivity and noise-protection against arc-welding, luminescent / incandescent lamps, the Sun, lightning discharges and all kinds of glimmering sources, irrespective of their "color" and intensity.

Main data

       "NABAT 4" is designed for use in complicated running conditions: extended working temperature range; enhanced mechanical influences; severe background situation; need of high running reliability.
Grade of envelope protection: IP67.
Explosion proof make marked "1ExibllCT6".
Protection form: "spark-proof circuit".
The main parameters meets Specification АДПК.42541.001ТУ.

Distinguished technical data:

  • Working temperature range: - 60 to +85°C.
  • Stability to solar noise illumination up to 100 000 lux.
  • It gives no false triggering when lit with incandescent lamps up to 5000 lux.
  • Stable to IR radiation from objects heated up to 400°C.
  • It has a system of in/external workability control with self-testing.

  • Spherical viewing angle: not under 100°; with an optical attachment: 5°.
  • This flame detector has an analogous output with unified output signal of current: 0 to 20 mA; it can co-operate with a centralized system of fire discovering and controlling fire extinguish; In that case:
    • In "Duty" mode, input current signal of the device is 4 mA; indicated by continuous lighting of the green LED;
    • In "Failure" mode (polluting of the input window, failure of photo-sensor or the electronic road), output current signal of the device is 2 mA; indicated by continued lighting of the red LED; there is realized continuous indicating any pollution of the input window;
    • In "Alarm warning" mode, output current signal is 12 mA. In this situation, we have discovered IR rays not reaching the level when we can say with certainty about arising of a flame in the fire focus; it is indicated by simultaneous lighting of the green and red LEDs. If vanishing the IR rays, the flame detector will return to "Duty" mode; if firing, the device will pass from the "Alarm warning" to "Alarm", output current signal being 20 mA.

       Analyzing data of the table permits to draw the following conclusions:
"NABAT" flame detectors:

  • possess much greater variability about the possibility of forming spectral characteristics of sensitivity of the radiation sensors, well then much greater adequacy to multiform kinds of flame and independence of possible optical background interference;
  • possess higher sensitivity, in particular to the most probable type of the focus: TП-5;
  • permit to discover fire focuses to discover focuses of ТП-2, ТП-3 types;
  • permit to realize the working mode of burst suppression not partially but in full measure;
  • permit to discover fire focuses when burning carbonless matters;
  • they are stable when action of modulated IR rays, the sunrays, sun patches and arc-welding flashes;
  • they can fulfill controlling gas burners and torches of deflecting gases;
  • they possess little power consumption, small mass and little outer dimensions;
  • they work yet when decreasing the ambient temperature down to minus 60°C;
  • they possess a high grade of envelope protection and the most effective kind of burst protection: "spark-proof circuit".
In that way, our offered flame detectors permit to realize parameters and characteristics which either not realized or not in full measure of them, at the best foreign analogs (except some exclusive versions having 125°C working temperature).
The prices of foreign analogs to our flame detectors made by companies "Det-tronics" (Detector Electronics Corporation, USA); "Spectrex Inc." (USA); "Siemens Building Technologies - Cerberus Division" (Switzerland), are in the $1200 - 2000 range. The prices of our NABAT flame detectors are $150 - 350.
