What is infrared flame detectors?
Infrared flame detectors – These sensors operate by using an infrared band. A small thermal imaging camera in these detectors can instantly detect the presence of hot gasses released anywhere near the infrared detector. Infrared waves can penetrate dust, smoke, fuel particles and oil films.
Which is one type of flame detector?
There are three types of flame detectors currently available. They are Infrared (IR), Ultraviolet (UV), and a combination of UV and IR. Infrared detectors have been available for many years, however, it has only been in recent times that technology has allowed for stable, accurate detection to occur.
What is the difference between UV and IR flame detector?
IR flame detectors solve a number of the false alarm problems associated with UV detection. They are not affected by hydrocarbon films; however, black body radiation does cause false alarms and water on the optical surface, attenuates the heat energy from a fire resulting in decreased sensitivity of the device.
What are IR detectors and UV detectors?
Infrared and Ultraviolet flame detectors are used in areas where traditional smoke detectors would be prone to false alarms. Infrared beam smoke detectors are used to provide “wide area” smoke detection.
What are the types of gas detectors?
Pellistor/Catalytic Bead (CB) Industrial Gas Detectors.
How many types of detectors are there?
The four types of fire detectors are ionization/photoelectric, photoelectric, ionization, and heat. The differences in these four types are found in how they detect a fire – heat is obviously triggered by temperature while the other three are from smoke.
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.
Where are flame detectors used?
Flame Detection Industrial and commercial applications include oil and gas pipelines, turbine enclosures, off-shore platforms, automotive manufacturing facilities, aircraft hangers, munitions plants, nuclear facilities, and many, many more.
What is the other name for flammable gas detector?
Catalytic (Pellistor) This detector is small and is used for detecting flammable gases from 0-100\% LEL.
What is point type gas detector?
Point combustible gas detectors are used to monitor the presence of flammable levels of hydrocarbon gas or vapor in industrial environments such as refineries and chemical plants. Point combustible gas detectors are therefore located at several dozen sites to monitor for gas leaks.
