DSL-340
The DSL-340 Dust Monitor uses the innovative Dynamic Detection Principle (DDP) to measure dust, smoke and particulate concentration present in an exhaust gas flow in a duct, stack or flue. A light beam emitted from the Transceiver (TRX) passes across the duct, stack or flue to a Reflector, which returns the light beam to the TRX. Particles moving through the beam will cause fluctuations in the intensity of light received by the TRX. When calibrated against standard reference measurements, the magnitude of the signal variation relates directly to the dust, smoke and particulate concentration.
• In-situ measurement directly in exhaust gas flow
• Innovative Dynamic Detection Principle, (DDP), measurement technique
• Measurement reading as mg/m3(when calibrated against standard reference measurements)
• Choice of interface options enabling easy integration into plant control system
• Free utility software for PC based setup, control and data logging

• Boilers and furnaces
• Crematoria
• Incinerators
• Post particulate removal systems such as filter bag houses, electrostatic precipitators or cyclones
• Marine industry for monitoring smoke emissions from diesel engines, incinerators and boilers
