Talentum Triple IR Flame Detector 16519
Talentum Triple IR Flame Detector 16519The sensor responds to low-frequency 1 to 15 Hz flickering IR radiation emitted from flames during combustion. IR flame flicker techniques enable the sensor to operate through a layer of oil dust water vapour or ice. Most other IR flame sensors respond to 4.3m light emitted by hydrocarbon flames. By responding to 1.0 to 2.7m light emissions from fires almost all flickering flames can be detected.Gas fires not visible to the naked eye e.g. hydrogen may also be detected. The triple IR photoelectric detectors IR responding to neighbouring IR wavelengths enable it to discriminate between flames and spurious sources of IR radiation. The combination of filters and signal processing allows the sensor to be used with a very low risk of false alarms in difficult situations characterised by factors such as flickering sunlight.Key FeaturesFireFault Pre-alarmRelay ContactsLatching or Non-latching4-20mAZones 1 21 2 and 22Ex tb IIIC T135C Db IP66 A21II 2GD Ex d IIC T4 GbATEX IECEx certifiedClass 1 Sensitivity to EN54-10 Detects 0.1m fire 25mExcellent Optical Interference ImmunitySelectable Output OptionsConventional 2 wireSelectable Response SpeedOptical Self TestLow Power ConsumptionLPCB CPD Approved to EN54-10
