Optical Flame Detectors

The optical flame detector consists of ultraviolet (UV) and infrared (IR) sensors. The most efficient flame detectors usually have several sensors (UV, UV/IR, IR3 or IR4). Like a fixed gas detector, an optical flame detector is usually a gas control It works in conjunction with the unit.

Most of our optical flame detectors SIL2 It is approved. They provide a high level of performance and reduce mean times between failures ( MTBF ) for more than 17 years .

Optical flame detection system, refineries , gas pipelines And pump stations , storage warehouses (solvents, alcohols, dyes), offshore platforms , printing facilities and also all ATEX It is well suited for highly hazardous industrial areas such as classified areas (explosive atmosphere).

These fire-exit monitoring units are specifically designed for hydrocarbon – flammable gas – (fuel, gasoline, jet fuel), methane (CH4). It is very effective in detecting LPG, hydrogen, polypropylene fires and, for example, paper fires in printing facilities.

• UV flame detector – Made with a UV-sensitive sensor. It produces an output signal based on radiation and compares it to an accurately calculated reference.
• IR flame detector – consists of an IR sensor sensitive to CO2 released as a result of fire.
• UV IR flame detector – consists of a UV-sensitive sensor combined with an IR sensor for the detection of hydrocarbons, hydrogen and metal flames with a high-speed response time (<150 ms). It requires the simultaneous response of both sensitive units.
• IR3 flame detector – three pyro-electric sensors detect IR radiations associated with different emission peaks. The IR3 sensor for hydrocarbon flame monitoring is immune to sunlight.
• IR4 flame detector – It is a combination of 4 infrared sensors to detect hydrocarbons and hydrogen flames from 5 to 65 meters away.
