Acoem Dynoptic - Model DSL-240 -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.
Dynamic Detection Principle
Innovative Dynamic Detection Principle (DDP) measurement technique
Less susceptible to drift
Immune to gradual reductions in absolute intensity of the light signal so less susceptible to drift
Unit of measure
Measurement reading as mg/m³ (when calibrated against standard reference measurements)
Calibration
Internal electronic calibration check capability
Rugged construction
Rugged 316 stainless steel construction
Interface options
Choice of interface options enabling easy integration
Free utility software
Free utility software for PC based set-up, control and data logging
Optional Operator Interface
Optional Operator Interface with different mounting configurations
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.
