Protect Your Industrial Facility from Fire Hazards

There are two main technologies for flame detection: UV/IR (Ultraviolet/Infrared) and MSIR (Multi-Spectrum Infrared). Both rely on line-of-sight detection of radiation emitted by flames in the UV and/or IR spectral bands.

UV/IR Flame Detection

Principle of Operation: A UV optical sensor is combined with an IR sensor to provide a dual-band detector sensitive to ultraviolet and infrared radiation froma flame. When both sensors detect radiation, the flame detector sounds an alarm.

Capable of high-speed responsiveness to both hydrocarbon and hydrogen-fueled flames

Suitable for indoor and outdoor use, with detection range and coverage area depending on the fuel type and selected sensitivity

Airborne debris and thick smoke might impact response time

Ideal for applications requiring a shorter detection range but broad coverage area

MSIR Flame Detection

Principle of Operation: Multi-Spectrum Infrared Flame Detectors combine various infrared spectral sensitivity frequencies to improve the detection of hazardous hydrocarbon flames and enhance false alarm rejection in demanding industrial environments.

Artificial Neural Network Technology provides greater accuracy and efficiency in hydrocarbon flame detection. Fires are often detected at a longer range than UV/IR detectors, although the field of vision is shorter

Suitable for applications in which airborne soot or smoke may precede an open flame/fire ignition

Provides excellent coverage for scenarios requiring extended detection range

FL5000 Flame Detector

The FL5000 MSIR Flame Detector extends the detecting range and reduces false alarms.

The MSA General Monitors^® FL5000 is an innovative multi-spectrum infrared (MSIR) flame detector with excellent false alarm discrimination over extended distances. It uses a multi-spectral optical IR array and advanced Artificial Neural Networks (ANN) to accurately distinguish between actual flames and the vast majority of false alarm sources.
