D-R 320 Scattered light dust monitor
D-R 320 Scattered light dust monitor
The new dust monitor D-R 320 is based on the back scattering principle. The light of a laser diode illuminates the dust particles in the measuring volume of the flue gas duct. The light scattered backwards by these particles is detected and evaluated. The D-R 320 does not require a light trap. The background light in the stack is detected by means of a special system with integrated dual detector and automatically compensated.
