Flame Detector




Flame Detector

A flame detector is a fire detection device that senses the presence of flame by detecting characteristic radiation emitted by fire (UV, IR, or both). Unlike smoke detectors, flame detectors can respond very quickly, often within milliseconds to a few seconds.


They are commonly used in

Oil & gas plants

Chemical industries

Power plants

Warehouses & fuel storage

Turbine enclosures

Battery energy storage systems (BESS)

Industrial UV IR Flame Detectors



Industrial UV IR Flame Detectors

Types of Flame Detectors

Detects UV radiation (180–260 nm range) emitted by flames

Very fast response (milliseconds)

Can be triggered by welding arcs or lightning (false alarm risk)


IR (Infrared) Flame Detector

Detects infrared radiation patterns from fire

More resistant to false alarms than UV

Works well in smoky environments


UV/IR Dual Flame Detector

Combines UV + IR sensing

Reduces false alarms

Faster and more reliable than single-spectrum detectors




Triple IR (IR3) Flame Detector

Uses three IR wavelengths

High immunity to false alarms

Detects hydrocarbon fires at long distances


Key Features to Look For

Detection range (10m–60m typical)

Explosion-proof certification (ATEX / IECEx for hazardous areas)

Fast response time

Immunity to false alarms

IP66/IP67 weather protection

Relay outputs / 4–20mA / Modbus integration
