How do I test my infrared flame detector?
How do I test my infrared flame detector?
– The portable flame sensor test unit should activate the flame detector at a distance of 3m within 20 seconds. – The detectors are fitted with internal IR LED’s that can be activated to optically test the detector. (The above tests apply to detectors at room temperature under normal factory lighting conditions.
How does a flame detector work?
Flame detectors comprise an electronic circuit with an electromagnetic radiation receiver. They are activated when they receive electromagnetic radiation from one or more defined wave lengths according to their design in the UV or infrared spectrum.
What kind of light does a flame detector detect?
Principles of Flame Detection Flames are known to emit electromagnetic radiation in the infrared (IR), visible light, and ultraviolet (UV) wavelengths depending on the fuel source. Because of this, optical flame-sensing technologies have been developed utilizing UV, UV/IR and multi-spectrum infrared.
What is a flame detector sensitive to?
Flame detectors are sensitive to glowing embers, coals, or actual flames with energy of sufficient intensity and spectral quality to initiate the detector. Infrared Detection. Infrared (IR) flame detectors work within the infrared spectral band.
Why is my boiler says flame failure?
If Flame Failure occurs frequently consult your Installer. This indicates that the Burner has fired up and is heating your system. This indicates that there is electricity to the Boiler. Turn the Central Heating Control Knob clockwise to increase or anticlockwise to decrease the boiler flow temperature.
Why do boilers flame failure?
Delayed ignition can be caused by a range of problems, including a restricted or weak pilot light. Also, low gas supply pressure can mean that there is too little gas at the burners, resulting in ignition problems. Another possible cause is too much primary air. This is air that’s mixed with gas before it’s ignited.
Can flame sensor detect heat?
Most fire detection technology focuses on detecting heat, smoke (particle matter) or flame (light) – the three major characteristics of fire. In contrast, because flame detectors are optical devices, they can respond to flames in less than a second. …
How do you detect a flame?
Principles of Flame Detection Most flame detectors identify flames by so-called optical methods like ultraviolet (UV) and infrared (IR) spectroscopy and visual flame imaging.
How many types of flame detectors are there?
There are three types of flame detectors currently available. They are Infrared (IR), Ultraviolet (UV), and a combination of UV and IR.
What are the specification of a flame sensor?
The IR flame sensor is used to detect the presence of fire or other infrared source (Flame or a light source of a wavelength in the range of 760 nm to 1100 nm can be detected)….Specifications.
