Spectrex 40/40 UV/IR Flame Detector – ATEX & IECEx Zone 1 Hazardous Area & SIL2
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).
The Spectrex 40/40 UV/IR is a flame detector manufactured by Spectrex with a combination of both UV and IR sensors and is available in two options. The 40/40L (& LB) model’s IR sensor operates at a wavelength of 2.5-3.0 μm and is able to detect hydrocarbon-based fuel and gas fires as well as metal and inorganic fires. The 40/40L4 (& L4B) is similar to 40/40L only differences being the wavelength of 4.5 μm and is only suitable for hydrocarbon-based fires.
Spectrex 40/40 UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. Both signals are then analysed for frequency, intensity and duration. When radiant energy is detected in both the UV and IR sensors an alarm is triggered and the UV sensor is able to prevent false alarms caused by solar radiation thanks to a special logic circuit.
The 40/40 UV/IR flame detector is weather resistant, highly dependable and SIL2 (TUV) approved to IEC 61508 due to increased reliability the flame detector now has a warranty period of 5 years.

Emerson Process Management Acquisition With Spectrex
In 2015 Spectrex were acquired by Emerson Process Management. The acquisition has strengthened Emerson’s product offering as they now have a comprehensive line of flame, gas and ultrasonic leak detector solutions used for safety monitoring in the industry.
➡ T&D Sales Team are able to support the specification and supply of their flammable and toxic gas detectors. Additionally, T&D are CompEx Certificated and competent in understanding hazardous area classifications and site requirements for the sale of explosion and flameproof equipment.
Flame, Heat, Gas Detectors & Detection Systems
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.
