Dust Monitor
Dynoptic dust monitors use the innovative Dynamic Detection Principle (DDP) to measure dust and particulate within exhaust gases from various manufacturing processes.
DDP, or optical scintillation as it sometimes referred to, measures the dynamic fluctuation in light transmission as dust particles move through a light beam. This dynamic fluctuation derives from temporal distributions of the dust particles which attenuate the light beam. The more dust present in the exhaust, the greater the amplitude of these fluctuations.
DDP instruments calculate the dynamic response, or the ratio of light variation to light intensity, which for particular applications, is proportional to dust concentration and when calibrated against standard reference measurements, this can be presented as a reading in mg/m3.
Unlike the standard transmission technique, DDP has immunity to gradual reductions in the absolute intensity of the light signal. Therefore, DDP instruments have the advantage that they are significantly less susceptible to drift with time, temperature or dirtying optics, than traditional opacity monitors and less sensitive to misalignment. In practice, this means that the instruments require less maintenance.
Dynoptic currently offers three different particulate monitors which each use the open path light transmission technique:
DSL-240 Dust Monitor
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.

DSL-340 Dust Monitor
The DSL-340 Dust Monitor is an optical instrument designed to measure the concentration of dust or particulate matter in exhaust gas passing through a duct, stack or flue.
The DSL-340 uses the innovative Dynamic Detection Principle (DDP) which measures fluctuations in the intensity of a light beam, using a folded beam Transceiver/Reflector arrangement. 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
