The laser beam passes across the stack or duct work and is reflected by the dust particles, the reflected light is then detected by the photoelectric sensor.
The laser beam passes across the stack or duct work and is reflected by the dust particles, the reflected light is then detected by the photoelectric sensor. The intensity of reflected laser signal is proportional to dust concentration, by which the resulting signal is analyzed to yield dust concentration.
