Cornstarch, corn dust, and saw dust are tested with the apparatus system with the method. This method used the light extinction coefficient of a dust cloud between two targets using a digital camera. This extinction coefficient is linearly related to the concentration of the dust, and the mass extinction coefficient is the key value for this measurement method. The mass extinction efficiency (K) depend greatly on the physical and chemical properties of the dust particles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for sensing suspended dust concentration","description":"The present disclosure provides to a novel two-target method for measuring the concentration of dust clouds, and an apparatus system that uses the novel two-target method.
