Pro-Sens

Dust Measurement

ProSens has been designed for a reliable dust measurement in clean sectors after filters. ProSens can be utilized at the following problem definitions:

  • Broken Bag Detection 
  • Trend Monitoring
  • Emission Measurement 

ProSens can be used in all metallic channels and pipes with a diameter up to 4000mm.

Features

  • Dust measurement also in large channel diameters
  • Output of dust concentration as absolute value
  • Measurement of dust concentration at high temperatures
  • Trend signal or absolute value

Basic principle of the ProSens is the triboelectric effect.

If the dust to be measured is constant, then the generated measuring signal is proportional to the dust concentration, even if there are dust deposits on the measuring probe.

Experience shows that the measuring method provides very exact results with little required maintenance.
