Explosion proof three band infrared flame detector with switch quantity

I. Overview

JTGB-UF-C36 ExThe point type infrared flame detector is strictly implemented by our company in accordance with the national standards of the People's Republic of ChinaGB15631-2008(Special fire detectors)GB3836.1-2021(Electrical equipment for explosive gas environments)GB3836.1-2021(Electrical equipment for explosive gas environments)GB4208-2017(Shell protection level)IPThe development and production of code related content.JTGB-UF-C36 ExThe point type infrared flame detector adopts 3 Narrow band pyroelectric infrared sensors with only different frequency bands are used to detect flames. Compared with previous infrared flame detectors that used single or dual sensors, they have outstanding performance stability and strong anti-interference

characteristic.

JTGB-UF-C36 ExPoint type infrared flame detectors are suitable for detecting flames generated by the combustion of various organic compounds, such as alkanes, alkenes, alkynes, aromatic hydrocarbons such as alcohol, n-heptane, gasoline, diesel, and flames generated by wood. They are not suitable for certain inorganic chemicals such as phosphorus, sodium, magnesium, sulfur, hydrogen, etc.JTGB-UF-C36 ExThe point type infrared flame detector adopts a widely used relay output method to achieve passive switch signals for alarm and fault, and has the characteristics of simplicity and strong adaptability.

3、 Main purpose and scope of application

JTGB-UF-C36 ExPoint type infrared flame detectors are suitable for detecting strong flame radiation during fires; Possible occurrence of liquid

Fire during non smoldering stages such as combustion; Need to respond quickly to flames; Places for the transportation, storage, and production of flammable materials; Environment such as substation facilities, engine rooms, and power stations; Places where open flames are strictly prohibited, such as liquefied gas stations, garages, gas stations, etc; Places where harsh environments and other detectors are difficult to function effectively.

JTGB-UF-C36 ExPoint type infrared flame detectors are not suitable for smoke diffusion before the appearance of flames; The mirror of the detector

The head is easily contaminated; The "line of sight" of the detector is easily obstructed by oil mist, smoke, water mist, and ice and snow; The combustible materials in the detection area are metals and inorganic substances; The detector is susceptible to direct or indirect exposure to light sources such as sunlight and incandescent bulbs; Strong air convection, if there is significant

Wind occasion; There are often places with strong arc light, radioactive substances, and strong infrared radiation.
