Single Pass Dust Monitor for monitoring dust emissions using DDP
The DSL-240 Dust Monitor is an optical instrument designed to measure the concentration of dust or particulate matter in the exhaust gas passing through a duct, stack or flue.
The DSL-240 uses the innovative Dynamic Detection Principle (DDP) in which a light beam emitted from the Transmitter passes across the stack to the Receiver, which measures fluctuations in the intensity of the received light. Increased dust or particulate density in the stack causes the amplitude of these fluctuations to increase. When calibrated against standard reference measurements, the amplitude of this signal relates directly to the dust concentration in the stack and this can be presented as a reading in mg/m³.
