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 flamme a flame more than 25m away and fast reacting.
How to Order Apollo is dedicated to ensuring that our customer service is aligned with your expectations. This makes the sensor in this frequency “solar blind”; however, sensitivity is reduced by sunlight. The biggest problem is our ignorance; some infrared detectors have an automatic detector window self test, but this deector test only monitors the occurrence of water or ice on the detector window.
This page was last edited on 19 Decemberat This makes detfctor sensors for use in outdoor applications very unresponsive to fires.
A common use in these installations is to cut off the supply of fuel if the flame fails, in detextor to prevent unburned fuel from accumulating. For infrared sensors also the lamination of the sensor material plays a part; it limits the cone of vision of the flame detector. The maximum sensitivity can be estimated by dividing the maximum flame area A by the square of the distance between the fire and the flame detector: Thermocouples are used extensively for monitoring flame presence in combustion heating systems and gas cookers.
In fact, during a fire, relatively sparsely UV energy and visible light energy is emitted, as compared glame the emission of Infrared radiation. Detecotr used in applications such as industrial furnaces, their role is to provide confirmation that the furnace is working properly; in these cases they take no direct action beyond notifying the operator or control system.
It is used for tracing defects in high voltage equipment and fire detection over high distances. The solar blind UV wavelength band is also easily blinded by oily contaminants. If you accept their use, simply click here to continue. Guise Medal Harry C. If necessary clean the optical surface with a cotton wipe wet with commercial liquid glass cleaner.
From Wikipedia, the free encyclopedia. This allows the detector to distinguish between non-flame IR sources and actual flames which emit hot CO 2 in the combustion process. Despite our best efforts, mistakes sometimes happen. They are also common in a variety of household gas furnaces and boilers.
A more exact relation – valid when the distance between the flame and detectod flame detector is small – between the radiation density, Eat the detector and the distance, Dbetween the detector and a flame of effective radius, Remitting energy density, Mis given by.
Multiple channel or pixel array sensors monitoring flames in flamee near IR band are arguably the most reliable technologies available for detection of fires.

Visible light will, however be transmitted through the water vapour screen, as can easily been irr3 by the fact that a human can still see the flames through the water vapour detsctor.
Triple-IR flame detectors compare three specific wavelength bands within the IR spectral region and their ratio to each other. A complete list of address settings is shown in the Installation Guide PP Accelerometer Angular rate sensor Auxanometer Capacitive displacement sensor Capacitive sensing Gravimeter Inclinometer Integrated circuit piezoelectric sensor Laser rangefinder Laser surface velocimeter Lidar Linear encoder Linear variable differential ie3 Liquid capacitive inclinometers Odometer Photoelectric sensor Piezoelectric accelerometer Position sensor Rotary encoder Rotary variable differential transformer Selsyn Sudden Motion Sensor Tachometer Tilt sensor Ultrasonic thickness gauge Variable reluctance sensor Velocity receiver.
Apollo is dedicated to ensuring that our customer service is aligned with your expectations. Key Features 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.
The range of a flame detector is highly determined by the mounting location.
This can be used to verify the presence of a Pilot flame. Most IR detectors are designed to ignore constant background Flzme radiation, which is present in all environments. 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: Active fire protection Passive fire protection.
This current can be used to verify flame presence and quality. A rlame LED alarm indicator may be connected to the flame detector.
Mini IR3 Flame Detector 2.5-10 m Range 20-20MI-3-F
Test the operation of the detector with either a portable flame sensor test unit or if practical a flickering yellow flame. Inform all appropriate personnel of intention to work on the flame detector. Smoke or deetector can limit the effective range of these, since they operate solely in the visible spectrum. A special frequency range is 4. The intense ionization within the body of a flame can be measured by means by the phenomena of Flame Rectification whereby an AC current flows more easily in one direction when a voltage is applied.
Further details may exist on the talk page. An Infrared detector which uses this frequency clame therefore solar blind. In flamd figure it can clearly be seen that “cold” CO 2 filters the solar radiation around 4.
