Dust dispersion during powder handling and processing is of great concern for both workers’ health and explosion risk. Dust emission locations in industries can vary during handling and processing. Dust concentration sensing would require the installation of sensors in every location prone to dust generation; for most, this is not a cost-effective approach.
Purdue University has developed a method of using a digital camera or photograph to measure the dust concentration based on two target intensity values. The method exploits the relationship between the suspended dust concentration and extinction coefficient. Calibrated equations for cornstarch, grain dust, and sawdust are now available. Most critically, this method does not require any training and can be implemented using “off-the-shelf” security cameras, or even a single photograph.
