Intelligent IR³ Flame Detector

A second advantage of this approach is, that the second flame detector is a redundant one, in case the first one is not working or is blinded. Weathershield, part flxmeFlame Sensor Test Unit and case, part no Contaminants like dust, oil and paint will reduce sensitivity.

The Intelligent IR3 Flame Detector is designed to protect areas where open flaming fires may be expected.

Flame Detectors: Mini IR3 Flame Detector m Range MIF

Full details of our service standards can be downloaded here. These detectors are sensitive to both UV and IR wavelengths, and detect flame by comparing the threshold signal of both ranges.

Different combustibles can even have a different angle of vision in the same flame detector. Fkame sun emits an enormous amount of energy, which would be harmful to human beings if not for the vapours and gases in the atmosphere, like water cloudsozonekr3 others, through which the sunlight is filtered. The horizontal angle of vision and the vertical irr3 of vision often differ; this is mostly caused by the shape of the housing and by mirroring parts meant for dtector self test.

These sensors measure heat and therefore are commonly used to determine the absence of a flame. These cameras can be used in complete darkness and operate both inside and outside. Guise Medal Harry C. Instead they are designed to detect suddenly changing or increasing sources of the radiation. Please expand the article to include this information. Hence, this detsctor range is used for flame detection by a few flame detector manufacturers in combination with other sensors like ultraviolet, visible light, or near infrared.

If necessary clean the optical surface with a cotton wipe wet with commercial liquid glass cleaner. Ugur; Dedeoglu, Yigithan; Cetin, A. They are also common in a variety of household gas furnaces and boilers. Stainless steel 2 axis adjustable mounting bracket, part no A near infrared IR sensor is especially able to monitor flame phenomena, without too much hindrance from water and water vapour.

Smoke or fog can limit the effective range of these, since they operate solely in the visible spectrum.

Apollo is dedicated to ensuring that our customer service is aligned with your expectations. 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. Now you are signed into MyApollo as an Apollo Customer, you can access all the portal features.

During burning of a hydrocarbon for example, wood or fossil fuels such as oil and natural gas much heat and CO 2 is released. Flame detector Heat detector Smoke detector. Otherwise, you may read our cookie policy here to find out more about how we use cookies, or learn how to block or disable cookies. With this constant c can, for the same flame detector and the same type of fire, the maximum distance or the minimum fire area be calculated: Such detectors can be used in large industrial process gas heaters and are connected to the flame control system.

A remote LED alarm indicator may be connected to the flame detector. One could say that the fire can be masked by other heat sources. The hot CO 2 emits much energy at its resonance frequency of 4. 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.

Flame detector

Condensed aerosol fire suppression Fire sprinkler system Fire sprinkler Gaseous fire suppression. Infrared IR or wideband infrared 1. Multi-infrared detectors make use of algorithms to suppress the effects of background radiation blackbody radiationagain sensitivity is reduced by this radiation.

Views Read Edit View history. Often one sensor looks at the 4. Visible light will, however be transmitted through the water vapour screen, as can easily been seen by edtector fact that a human can still see the flames through the water vapour screen.

A salt film is also harmful, because salt absorbs water.

This makes the sensor in this frequency “solar blind”; however, sensitivity is reduced by sunlight. Disabling cookies may impair your experience of this website as some functionality relies on cookie information, and you may not be able to access certain areas of the site. For infrared sensors also the lamination of the sensor material plays a part; it limits the cone of vision of the flame detector. However, water vapour, fog or light rain also makes the sensor almost blind, without the user knowing.

A poor flame or one foame is lifting off the burner may also derector the continuity. It is also possible to mix visible light information monitor with UV or infrared information, in detecttor to better discriminate against false alarms or to improve the detection range.

The solar blind UV wavelength band is also easily blinded by oily contaminants.

APO – Intelligent IR³ Flame Detector

International Conference on Image Processing: Multiple channel or pixel array sensors monitoring flames in the near IR band are arguably the most reliable technologies available for detection of fires.

From Wikipedia, the free encyclopedia. Flae severe disadvantage is that almost all radiation can be absorbed by water or water vapour ; this is particularly valid for infrared flame detection in the 4.
