Dust opacity monitor DSL-340

gas

Double pass dust monitor for monitoring dust emissions using ddp 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. Features 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 MkIII 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. Optional accessories Operator interface (OI) 90-260 Vac model available Mounting flange installation kit Laser alignment tool to assist with installation Air purge blower kit (110 Vac / 230 Vac / 415 Vac) Compressed air purge kit
