DSL-220M

DSL-220M

With Port Authorities around the world increasingly regulating emissions from ships, the DSL-220M Smoke Opacity Monitor is an optical instrument specifically designed to measure the visible opacity of smoke emissions within the marine industry.

The DSL-220M uses the single pass light transmission measurement technique, with Transmitter/Receiver arrangement. A light beam emitted from the Transmitter passes across the stack to a Receiver, which measures the intensity of the received light. Increased smoke density in the stack gas attenuates the transmitted light and causes the intensity of the received light to fall. This reduction in intensity is measured and presented as % opacity. The higher the level of smoke present, the more light lost and therefore, the greater the opacity

Features
  • Lloyds Type Approved smoke opacity monitor designed specifically for the marine industry
  • In situ measurement directly in exhaust gas flow
  • Measurement reading as % Opacity
  • Modulated green LED source for long lifetime stability and immunity to ambient light
  • Intelligent’ sensor so no requriement for a local control unit
  • Choice of interface options enabling easy integration
  • Optional Operator Interface with different mounting configurations
Benefits
  • Simple to install, commission and operate with an excellent reliability record
  • Rugged design with no moving parts so low maintenance
  • Latched head and lid design to enable ease of access for installation and maintenance
  • Free utility software for PC based set-up, control and data logging
