The aluminum flame detector housing has a window near the sensor and is provided with a protective mirror, and the bottom of the housing is provided with a bracket. The detection method is based on the reasonable selection of the two bands of the detector, combined with the flame flicker frequency identification technology and the dual-band signal processing software algorithm, to determine the fixed base value mode, the compensation base value mode and the flicker frequency mode respectively, so as to realize the detection of the background light. It has high flame detection sensitivity when present, and no false alarm occurs when the background light interference is modulated to the flame flicker frequency.
The basic principles of dual-band infrared flame detectors and triple-band infrared flame detectors are the same, but in dual-band infrared flame detectors, two pyroelectric sensing elements are used as infrared sensors, and through two signal processing channels, It responds to the radiative changes of the flame light signal and the background light signal in two bands in the infrared spectral region, respectively.
The three-band infrared flame detector has three infrared sensors, which can respond to the radiation changes of the flame light signal and the background light signal in the three bands of the infrared spectral region. Compared with the dual-band infrared aluminum flame detector housing, the three-band infrared aluminum flame detector housing has higher sensitivity. Therefore, users who have high requirements on the sensitivity of the infrared aluminum flame detector housing can choose a three-band infrared flame detector. Generally, three-band infrared flame detectors are used for fire protection.
