Dust Monitor

LSS2004 Dust Concentration Monitor is a new generation product, which can work continuously for a long time in very harsh circumstances, such as in the wind, the rain, the thunder and lightning, the dust, the high temperature and so on.
Principle of Operation
LSS2004 is a laser-based backscatter particulate monitor that is designed to measure dust loading of combustion exhaust gas stream. The electrical output from the LSS2004 is proportional to the light scatted back from the particles in the gas stream .The high stable laser signal source projected into the gas flue and those particles can reflect the light whose intensity is proportional to the dust content of the gas stream. The LSS2004 receives the weak laser signal which is reflected by particles, then calculates the concentration of dust by specific algorithm.
