• The Flame Detector UV/IR2 is designed to protect areas where open fires may be expected and detects most flames from hydrocarbon fires with 4.3 μm emissions through to invisible fires such as hydrogen. The Flame Detector is sensitive to flickering, low frequency (1-15 Hz) infra-red radiation along with ultra-violet emitted by flames during combustion. It has a UV sensor and two IR sensors which respond to different wavelengths of both the ultra-violet and the infra-red spectrum. The signals from these sensors are processed by the detector and checked for characteristics of a flame. The simultaneous detection of both the UV and the IR light by the sensors will signal an alarm. False alarms from flickering sunlight, arc welding and lightning are eliminated by a combination of UV and dual IR signal processing techniques. The UV/IR2 Flame Detector has selectable output options of relay contacts of 4 to 20 mA signal as standard.
