Dust opacity monitor DSL-330

gas

Double pass particulate monitor for monitoring particulate and smoke emissions The DSL-330 Particulate Monitor is an optical instrument designed to measure the concentration of dust or particulate matter in an exhaust gas passing through a duct, stack or flue. Features GAS FLOW'S MEASUREMENT In situ measurement directly in exhaust gas flow UNIT OF MEASURE Measurement reading as particulate as mg/m³ MODULATED GREEN LED SOURCE Modulated green LED source for long lifetime stability and immunity to ambient light RUGGED CONSTRUCTION Rugged 316 stainless steel construction CALIBRATION In-situ zero and calibration check facility 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-330 uses the double pass light transmission measurement technique, with a folded beam Transceiver/Reflector arrangement. A light beam emitted from the Transceiver (TRX) passes across the duct, stack or flue to a Reflector, which then returns the light to the Transceiver where the intensity of the received light is measured. Increased particulate density in the stack gas attenuates the transmitted light and causes the intensity of the received light to fall. When calibrated against standard reference measurements, this reduction in intensity can be used to calculate the particulate concentration and present 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
