The Talentum Intrinsically Safe (IS) dual Infra-Red (IR²) Flame Detector is designed to protect areas where open fires may be expected and detects almost all flames, including hydrocarbon fires with 4.3 m emissions through to invisible fires such as hydrogen.
The IR Flame Detector is sensitive to flickering, low frequency (1- 15Hz) infra-red radiation emitted by flames during combustion even if the lens is contaminated by a layer of oil, dust, water, vapor or ice.
This detector has two IR sensors which respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation. False alarms from flickering sunlight are avoided by a combination of filters and signal processing techniques.
The Talentum IR detector has selectable output options of relay contacts or 4-20mA signal, as standard.
