This allows the detector to distinguish between non-flame IR sources and actual flames which emit hot CO 2 in the combustion detectro. A flame detector can often respond faster and more accurately than a smoke or heat detector due to the mechanisms it uses to detect the flame. These little explosions cause the flickering of the flame. The cone of vision of a flame detector is determined by the shape and size of the window and the housing and the location of the sensor in the housing. Fire blanket Fire bucket Fire extinguisher.

A non-hydrocarbon fire, for example, one from hydrogendoes not show a CO 2 peak lr3 4. A severe disadvantage is that almost all radiation can be absorbed by water or water vapour ; retector is particularly valid for infrared flame detection in the 4.

A salt film is also harmful, because salt absorbs water. The Intelligent IR3 Flame Detector is designed to protect areas where open flaming fires may be expected.

Stainless steel 2 axis adjustable mounting bracket, part no Product Information The Intelligent IR3 Flame Detector is designed to protect areas where open flaming fires may be expected. Triple-IR flame detectors compare three specific wavelength bands within the IR spectral region and their ratio to each other.

Intelligent IR³ Flame Detector

From Wikipedia, the free encyclopedia. Visually check the exterior of detectkr detector for any mechanical or corrosive damage. These sensors measure heat and therefore are commonly used to determine the absence of a flame. A high sensitivity on the edges of the angle of vision provides advantages for the projection of a flame detector.

The hot CO 2 emits much energy at its resonance frequency of 4. Oops… Despite our best efforts, mistakes sometimes happen. Inspect the detector viewing window for any build-up of dust or other contaminants on the optical surface. Triple IRs, like other IR flaje types, are susceptible to blinding by a layer of water on the detector’s window.

Mini IR3 Flame Detector 2.5-10 m Range 20-20MI-3-F

False alarms due to such factors as flickering sunlight are avoided by a combination of filters and signal processing techniques. Dual- or multi-infrared detectors suppress the effects of heat radiation by means of sensors which detect just off the CO 2 peak; for example at 4.

This flickering is caused by the fact that the aspirated oxygen and the present combustible are burning and concurrently aspirate new oxygen and new combustible material. Register or sign in to add products to your project list. Such detectors can be used in large industrial process gas heaters and are connected to the flame control system.

If necessary clean the optical dftector with a cotton wipe wet flamr commercial liquid glass cleaner. This site uses cookies in order to optimise your experience of the site. Active fire protection Passive fire protection. Please expand the article to include this information. 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.

APO – Intelligent IR³ Flame Detector

Retrieved from ” https: With this constant c can, for the same flame detector and the same type of fire, the maximum distance or detsctor minimum fire area be calculated: Problems with boilers failing to stay lit can often be due to dirty flame sensors or to a poor burner surface with which to complete the electrical circuit. Inform all appropriate personnel on completion of the maintenance work and if necessary record this work.

A fire emits radiation, which human eye experiences as the visible yellow red flames and heat. In this equipment the information of an UV camera mixed with visible image information. Existing customers Please email your order to us at: Visible light will, however be transmitted through the water vapour screen, as can easily been seen by the fact that a human can still see the rlame through the water vapour screen.

In other words, the flame detector becomes less sensitive. A wide cone of vision does not automatically mean that the flame detector is better.

This causes a peak in the total radiation emission and can be well detected. A flame detector is a sensor designed to detect and respond to the presence of a flame or fireallowing flame detection. Not all manufacturers of flame detectors use sharp filters for the 4. The cause is similar to what a fire fighter does if he approaches a hot fire: The flame detector is designed to give years of trouble-free operation with minimal attention.

Infrared IR or wideband infrared 1. For some detectoor the flame detector needs to be aligned precisely to take care that it does not detect potential background radiation sources.
