ABB火检光纤SF810介绍
ABB火焰探测光纤SF810系列，具有多年的研发经验。
红外火焰探测器的原理：火焰中有大量可见光和0.9m以上的红外线。这些波长的光不易被煤尘，水蒸气和其他燃烧产物吸收，因此适用于检测煤粉火焰，重油火焰以及惰性气体含量高的燃料的适当燃烧。红外火焰检测通过检测燃烧火焰发出的红外线强度和火焰频率来确定火焰的存在。该探头使用硫化铅光电管或硅光电二极管。由于炉膛的火苗在火焰区被燃烧，因此火苗的频率通常不超过2HZ。因此，红外火焰探测器可以通过过滤器电路区分燃烧器火焰和背景火焰。 

ABB flame detection fiber SF810 series, with many years of research and development experience.
Principle of Infrared Flame Detector: There is a large amount of visible light in the flame and infrared rays above 0.9m. These wavelengths of light are not easily absorbed by coal dust, water vapor, and other combustion products, so it is suitable for detecting pulverized coal flame, heavy oil flame, and suitable combustion of a fuel with a large inert gas content. Infrared flame detection determines the presence of flame by detecting the intensity of the infrared rays emitted by the combustion flame and the flame frequency. The probe uses a lead sulfide photocell or a silicon photodiode. Since the furnace flicker is completely burned in the flame zone, the flame flicker frequency usually does not exceed 2HZ. Therefore, the infrared flame detector can distinguish between the burner flame and the background flame through the filter circuit.
