Durag d-r 820 manual
The D-R operates using the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam caused by the dust content in the measuring path is measured and evaluated. The sensitivity scales up with growing duct www.doorway.rug: manual. D-R F Measuring principle A defined partial current is withdrawn from the exhaust gas current. This par-tial current is continuously heated and diluted with clean, heated air directly in the sampling probe. This immedi- ately lowers the relative moisture and aerosols get evaporated in the heated probe. The partial current is optically. This manual is intended to assist you in starting to use your DURAG product. In this publication you will find information and technical data for planning, installation / commissioning, operation and maintenance of the D−R

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.
