FWE200DH Scattered Light Dust Measuring Device

Brand: Sick AG

The FWE200DH dust measuring device is designed to continuously measure dust concentrations in wet flue gas. 

The gas is extracted via a gas sampling probe and heated above the dew point. 

Droplets in the gas are vaporized, making it impossible for them to falsify the measurement results. 

The highly sensitive scattered light measurement principle enables accurate measurements even at low dust concentrations.

The FWE200DH meets the requirements of EN 14181 and EN 15267.
Features
  • Reliable and proven dust measurement in wet gases
  • Economic operation due to very few consumable parts and very low installation effort
  • Very low maintenance since no moving parts come into contact with the aggressive gas
  • Very long service life due to intelligent design
