Three-band infrared flame detector

When a substance burns, it produces smoke and heat, and also produces visible or invisible light radiation that is not found in the atmosphere. Flame detector, also known as photosensitive fire detector, is a fire detector used to respond to the light characteristics of fire, that is, to detect the light intensity of flame burning and the flicker frequency of flame. Infrared flame detector is a flame detector that is sensitive to the longer wavelength infrared light radiation in the flame. According to the different detection bands, it is divided into single band, dual band and three band.
