DSL-330

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.

DSL-330 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
  • Air purge blower kit (110 Vac / 230 Vac / 415 Vac)
  • Compressed air purge kit
  • Reference filters for routine calibration check of the instrument

Benefits

  • Simpler installation than single pass opacity monitors
  • Better accuracy over shorter path lengths than single pass opacity monitors
  • Rugged design with no moving parts so low maintenance
  • Latched head and lid design to enable ease of access for installation and maintenance

Why do you need DSL-330 ?

Ideal for monitoring particulate levelsin the exhaust gas of industrial combustion or air filtration processes.
