Do you know how a flame detector works?

发布日期: 2018.08.16 Back to list source: Release date: 2018.08.16

Flame detector : When a substance burns, it generates visible light radiation while generating smoke and releasing heat. The flame detector is also called a photosensitive fire detector, which is a characteristic used to respond to a fire. It is a kind of fire detection device that diffuses the light intensity of the flame burning and the flicker frequency of the flame.

According to the light characteristics of flames, there are currently two types of flame detectors: one is an ultraviolet detector that is sensitive to short-wavelength optical radiation, and the other is an infrared detector that is sensitive to long-wavelength optical radiation.

The UV flame detector is a sensitive high-intensity flame emission ultraviolet spectrum. It uses a solid substance as a sensitive element, such as silicon carbide or aluminum nitrate, and an inflatable tube as a sensitive element.

The infrared detector basically includes a filtering device and a lens system, which are used to screen out unwanted wavelengths, and the incoming light energy is concentrated on a phototube or a photoresistor that is sensitive to infrared light.

The flame detector should be installed in a place where an explosion occurs instantly. Such as petroleum, explosives and other chemical manufacturing production and storage places. The Ranxin UV flame detector is only sensitive to the ultraviolet light generated, has no response to the high temperature radiation of the light and the furnace, and has strong anti-interference.
