D-R 320

D-R 320

The new scattered light dust monitor to detect lowest to medium dust concentrations in dry flue and process gas.

The D-R 320 is based on the back-scattered light principle. Thereby the light of a red laser diode illuminates the dust particles in the measuring volume of the flue gas duct. The light scattered backward by these particles is detected and evaluated.

A unique feature of the D-R 320 is the automatic background light compensation with means of a patented optical system with dual detector. This allows for an easy and quick Installation without any adjustment. A light trap is not required.

  • Single sided installation on a standard flange
  • Easy startup without adjustment automatic background light compensation without light trap
  • Automatic zero and reference point check
  • Automatic contamination control and correction integrated purge air regulation and purge air control
  • Minimum maintenance
  • EN 15267 certified
