LPD - in line Large Particle Detector

The Large Particle Detector is a compact particle detector for applications in ultra pure and chemical aggressive media. The detection limit of 1 µm-particles makes this sensor particular suitable for in-line process monitoring and control of complex and high concentrated submicron dispersions, micro-emulsions, polishing slurries or pure fluids.
The integrated evaluation unit with a LCD-display, the RS485 interface as well as the free programmable digital or analogue output minimizes additional hardware requirements and guarantees an easy connectivity to a PC or PLC.

Applications

  • Large particle detection in pure fluids and in slurries
  • In-line quality monitoring of CMP slurries
  • Prevention of micro scratches at polishing processes
  • Filter control
  • Optimization of filter lifetime
  • Defect detection in supply systems
  • Ultrapure and chemical aggressive liquids
