Libelle Fluid Control
Libelle Fluid Control reduziert aufwendige Restschmutzanalysen und bietet eine direkte Eingriffsmöglichkeit bei Veränderungen des Reinigungsmediums

Libelle Fluid Control

Monitoring the condition of the bath

Every cleaning process requires a sufficiently pure cleaning medium. When the bath is depleted, sufficient cleaning results can no longer be achieved. It is thus essential that the operator of the cleaning system knows the condition of the bath. Only then can he ensure constant component cleanliness. Libelle Fluid Control permanently measures the condition of the bath. The results are output via the system controller or optionally via the Libelle Data Control.

Fields of application:

  • any cleaning process
  • impurity mixture of particles and other contaminations
  • fast and precise evaluation of bath quality
  • allows direct intervention when the cleaning medium changes (e.g. filter failure)
  • reduction of rejects caused by insufficient cleaning
  • reduction of expensive residual contamination analyses
  • optimization of bath life and bath change
  • process reliability

Measuring principle

Measurement of the absorption properties of the cleaning fluid: If absorption increases in the visible light wave range, the fluid is contaminated with more impurities.

The measurement of the Libelle Fluid Control clearly shows how bath contamination develops over time. The filter failure on 10 September could have gone undiscovered without the Libelle, resulting in a large number of rejects. A simple filter change redressed the problem easily. The diagram also clearly illustrates the marked improvement of the bath condition after the bath change.
