Where are UV flame detectors used?
UV/IR flame detectors are used in:
- Hydrogen stations.
- Gas-fueled cookers.
- Industrial heating and drying systems.
- Domestic heating systems.
- Industrial gas turbines.
What by product of fire is detected by UV IR detectors?
FLS-UV-IR: A UV and IR detector that detects hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires. The UV sensor has a special logic circuit that prevents false alarms from solar radiation.
What is the function of UV type detectors?
UV/UV-VIS detectors are most frequently used to measure components showing an absorption spectrum in the ultraviolet or visible region. A UV detector employs a deuterium discharge lamp (D2 lamp) as a light source, with the wavelength of its light ranging from 190 to 380 nm.
What is IR 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). It can be used in fire fighting robot or heat seeking robot.
How do UV flame sensors work?
A UV/IR flame detector consists of ultraviolet (UV) and infrared (IR) sensors that are joined together in a single apparatus. UV sensors work by detecting the UV radiation emitted by the flame and are sensitive to a wide range of flammable fuels including hydrocarbons, sulfur, hydrazine and ammonia.
How do UV sensors work?
UV sensors measure the power or intensity of incident ultraviolet (UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation, but is still longer than x-rays. UV sensors are used for determining exposure to ultraviolet radiation in laboratory or environmental settings.
How does a UV IR detector work?
Does fire emit infrared?
Far infrared waves are thermal. In other words, we experience this type of infrared radiation every day in the form of heat! The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared.
What is UV IR?
IR and UV radiation are a small part of the electromagnetic spectrum. The visible light has a wavelength of 380 nm to 760 nm. The area alongside with a longer wavelength is the IR spectrum. The area next to the visible light, with a shorter wavelength, is the UV spectrum.
How does a UV and IR detector work?
The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.
Can a UV / IR sensor be used for gas detection?
World-class UV/IR flame detectors are one of the several useful fixed fire and gas detection instruments available from MSA. Flammable and toxic gas sensors can be used in combination with the improved system provided by MSA in order to achieve the ultimate life safety and facility fire protection.
How does a UV sensor detect a fire?
UV sensors work by detecting the UV radiation emitted by the flame and are sensitive to a wide range of flammable fuels including hydrocarbons, sulfur, hydrazine and ammonia. The main radiant emission band for hydrocarbon fueled fires ranges between 4.3 and 4.4 microns, it is an infrared emission that the IR sensors can detect with ease.
Which is the best UV / IR flame detector?
Ultra-fast detection of hydrocarbon and hydrogen fires are possible with Fike optical flame detectors. Their resistance to weather conditions and false alarms, and ability to detect smoke and oil mist with Fike Video Analytics, make UV/IR optical detection ideal for high-risk environments.
