IR3 Flame Detector ▷ Sensitivity according to EN Class 1: m² flames at 25m. ▷ Low risk of false alarms due to different IR. The Intelligent IR3 Flame Detector is designed to protect areas where open flaming fires may be expected. It is sensitive to low frequency, flickering infra-red . The Triple Infra-red (IR3) Flame Detector is designed to protect areas where open fires may be expected. The IR3 Flame Detector is sensitive to low frequency .

A rule of thumb is, that the mounting height of the flame detector is twice as high as the highest object in the field of view. False alarms can be caused by other hot surfaces and background thermal radiation in the area.
Triple-IR flame detectors compare three specific wavelength bands within the IR spectral region and their ratio to each other. Only registered customers can save products to project lists. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line such as a propane or a natural gas lineand activating a fire suppression system.
It must be emphasized, however, that the square root in reality is not valid anymore at very high distances. Infrared flame detectors suffer from Infrared heat radiation which is not emitted by the possible fire. Closed-circuit television or a web camera can be used for visual detection of wavelengths between 0. DoP – Declaration of Performance.
A complete list of address settings is shown in the Installation Guide PP Please email your order to us at: Water on the detector’s lens will greatly reduce the accuracy of the detector, as will exposure to direct sunlight.
Register or sign in to add products to your project list. In fact, during a fire, relatively sparsely UV energy and visible light energy is emitted, as compared to the emission of Infrared radiation.
Often one sensor looks at the 4. A common use in these installations is to cut off the supply of fuel if the flame fails, in order to prevent unburned fuel from accumulating. Oops… Despite our best efforts, mistakes sometimes happen.

Loop-powered Sensitive to flickering IR radiation Detects through films of oil, dust, water and ice Responds to flickering flames, including those invisible to the naked eye False alarms due to lighting or flickering sunlight are minimised Compatible with Discovery and XP95 protocols.
It is also possible to mix visible light information monitor with UV ri3 infrared information, in order to better discriminate against false alarms or to improve the detection range. It looks like a static picture, but in reality the energy fluctuates, or flickers. Every multi infrared flame detector is negatively influenced by this effect, regardless how expensive it is.
Flame Detectors: Mini IR3 Flame Detector m Range MIF
Application Flame detectors are used when detection is required to be unaffected by convection currents, draughts or wind; tolerant of fumes, vapours, steam, dust and mist; responsive to a flame more than 25m lr3 and fast reacting. Pyroelectric sensors operating at this wavelength can be relatively cheap.
Inform all appropriate personnel on completion of the maintenance work and if necessary record this work. Fire blanket Fire bucket Fire extinguisher. Sometimes a moving hand is sufficient to trigger an IR flame detector.
The hot CO 2 emits much energy at its resonance frequency of 4. They usually act as both flame quality monitors and for flame failure detection. This page was last edited on 19 Decemberat New customers Please email your order to us at: This law is equally valid for all optical flame detectors, including video based ones. The big economical advantage is that detector windows can be made of quartz instead of expensive sapphire. Near infrared IR array flame detectors 0.
This article is missing information about the history of the subject. IR3 detectors can detect a 0. For some applications the flame detector needs to be aligned dstector to take care that it detectpr not detect potential background radiation sources. False alarms due to such factors as flickering sunlight are avoided by a combination of filters and signal processing techniques.
Mini IR3 Flame Detector 2.5-10 m Range 20-20MI-3-F
The flame detector is designed to give years of trouble-free operation with minimal attention. Inform all appropriate personnel of intention to work on the flame detector. Industrial and Process Furnaces: From Wikipedia, the free encyclopedia.
