Talentum UV/IR2 Flame Detector (16521) Copper-Free Aluminum Housing, Flameproof EXD

The Talentum Ultra-Violet, dual Infra-Red (UV/IR²) Flame Detector is designed to protect hazardous areas where open fires may be expected and detects almost all flames, including hydrocarbon fires with 4.3 microns;m emissions through to invisible fires such as hydrogen. The UV/IR2 Flame Detector is sensitive to flickering, low frequency (1-15Hz) infra-red radiation emitted by flames during combustion. This detector 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 Talentum UV/IR2 detector has selectable output options of relay contacts or 4-20mA signal, as standard.
