Spectrex 40/40L-LB UV/IR Flame Detector – ATEX & IECEx Zone 1 Hazardous Area & SIL 2

Spectrex 40/40L-LB UV IR Flame Detector

Spectrex 40/40L-LB UV IR Flame Detector

Flame Detector

Hazardous Area | ATEX Certified

Spectrex flame detectors are trusted and specified throughout the UK and international hazardous area industries to provide reliable flame detection in potentially explosive atmospheres according to IECEx and ATEX (Zone 1 & Zone 2).

Model 40/40L (or LB, with Built-in-test option) by Spectrex provides a combination of UV and IR sensors, where the IR sensor operates at a wavelength of 2.5-3.0 µm, and can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires.

The Spectrex UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared  portions of the electromagnetic spectrum. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.

The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.

Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and is SIL2 (TUV) approved to IEC 61508.

Flame, Heat, Gas Detectors & Detection Systems

ATEX Beacon

Hazardous area industries including offshore oil/gas platforms and FPSOs, onshore oil refineries, processing plants, pipelines, storage farms and LPG/LNG plants all utilise or produce a wide range of hazardous flammable liquids and gases that can be detected using correctly specified flame and gas detectors.

Detecting toxic and flammable gases requires the detectors to be classified and certified according to the specific IECEx or ATEX standard – we distribute flame detectors manufactured by Spectrex to operate in the harshest environmental conditions including self-contained stand-alone devices designed for direct connection to control and alarm systems or automatic fire extinguishing systems.

Our range of Hazardous Area Fire & Gas Detection System products also includes Explosion Proof Warning Systems – comprehensive range of intrinsically safe, flameproof and explosion proof alarm sounders, sirens, bells and horns, loudspeakers and beacons.
