Talentum 16521-00 UV IR2 Flame Detector Flameproof Exd
Talentum 16521-00 UV IR2 Flame Detector Flameproof ExdThe Talentum flameproof Ultra-Violet dual Infra-Red UVIR 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 m emissions through to invisible fires such as hydrogen. The UVIR 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 UVIR detector has selectable output options of relay contacts or 4-20mA signal as standard.Key FeaturesHighest immunity to false sourcesSolar blindTolerant of fumes vapours dust and mistSuitable for indoor and outdoor areasUnaffected by convection currents draughts or windProven response to multiple fuel typesMulti-spectrum detectionSelectable output optionsSelectable response speedSelectable sensitivity levelsBuilt in auto and manual testLow current consumptionFast response to fireApplicationsChemical PlantsNuclear Power SitesEngine RoomsSpray BoothsPharmaceutical ProductionMilitary ApplicationsMarine IndustryPrinting RefineriesFuel loading racksStorage tanksAircraft hangersPetrochemical onshoreoffshoreBiomass storage and handlingLNGLPG productionApprovalsATEXII 2GD Ex d IIC T6Zones 1 21 2 and 22Worldwide approvals include EN5410 with VdS and LPCB
