IFD-E

The IFD-E Flame Detector is designed to protect areas where open fires may be expected and detects almost all flames, including hydrocarbon fires with 4.3 μm emissions through to invisible fires such as hydrogen. The Detector is sensitive to flickering, low frequency (1- 15 Hz) infrared radiation emitted by flames during combustion even if the lens is contaminated by a layer of oil, dust, water, vapour or ice. This detector has three 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 Detector has selectable output options of relay contacts or 4-20 mA signal, as standard.
