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.
