IR3 FLAME DETECTOR PDF

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 .

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.

Guise Medal Harry C. If you accept their use, simply click here to continue. 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: Despite our best efforts, mistakes sometimes happen. The horizontal angle of vision and the vertical angle of vision often differ; this is mostly caused by the shape of the housing and by mirroring parts meant for the self test.

A disadvantage is that the radiation energy of a possible fire must be much bigger than the present background heat radiation.

IR3 detectors can detect a 0. In other words, the flame detector becomes less sensitive. Every multi infrared flame detector is negatively influenced by this effect, regardless how expensive it is. Geophone Hydrophone Microphone Seismometer. The range of a flame detector is highly determined by the mounting location.

Not all manufacturers of flame detectors use sharp filters for the 4. A non-hydrocarbon fire, for example, one from hydrogendoes not show a CO 2 peak on 4. Retrieved from ” https: This current can be used to verify flame presence and quality.

In fact, during a fire, relatively sparsely UV energy and visible light energy is emitted, as compared to detectod emission of Infrared radiation. Retrieved 9 August 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.

Industrial and Process Furnaces: Visually check detectot exterior of the detector for any mechanical or corrosive damage.

APO – Intelligent IR³ Flame Detector

Test the operation of the detector with either a portable flame sensor test unit or if practical a flickering yellow flame. Register or sign in to add products to your project list. A 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.

A poor flame or one that is lifting off the burner may also interrupt the continuity. Inform all appropriate personnel of intention to work on the flame detector.

A wide cone of vision does not automatically mean that the flame detector is better. Please note… Remember to quote your account number and purchase order number on any order correspondence. This helps minimize false alarms. Compare 0 Products Add To Compare 0 of 4 max. Inspect the detector viewing window for any build-up of dust or other contaminants on the optical surface.

This law is equally valid for all optical flame detectors, including video based ones. A near infrared IR sensor is especially able to monitor flame phenomena, without too much hindrance from water and water vapour. Active pixel sensor Angle—sensitive pixel Back-illuminated sensor Charge-coupled device Contact image sensor Electro-optical sensor Flame detector Infrared Kinetic inductance detector LED as light sensor Light-addressable potentiometric sensor Nichols radiometer Optical fiber Photodetector Photodiode Photoelectric sensor Photoionization detector Photomultiplier Photoresistor Photoswitch Phototransistor Phototube Position sensitive device Scintillometer Shack—Hartmann wavefront sensor Single-photon avalanche diode Superconducting nanowire single-photon detector Transition edge sensor Tristimulus colorimeter Visible-light photon counter Wavefront sensor.

In this equipment the information of an UV camera mixed with visible image information. A flame detector is a sensor designed to detect and respond to the presence of a flame or fireallowing flame detection.

Flame detector

These sensors measure heat and therefore are commonly used to determine the absence of a flame. Fire blanket Fire bucket Fire extinguisher. This is a resonance frequency of CO 2. These cameras can be used in complete darkness and operate both inside and outside. Most IR detectors are designed to ignore constant background IR radiation, which is present in all environments.
