Online Monitoring of the cleaner concentratration and bath contamination

- Efficient cleaning of industrial parts and treatment of surfaces by inline analytical technology -


Concentration fluctuations in cleaning and treatment baths
affect the bath quality and resource efficiency if meeting desired nominal values ​​is not monitored continuously or only imprecisely.
Since the initial cleaner concentration decreases during the process, the replenishment will be either too much or too little having no proper bath monitoring. Underdosing of the cleaner results in not meeting the cleanliness requirements; overdosing results in wasting of valuable resources.

Also the degree of bath contamination subjects
to fluctuations that influence the cleaning performance and resource efficiency. During the cleaning process, the degree of contamination increases steadily.
Having the information about reaching the contamination limit, bath changes can be done efficiently. So costs due to frequent bath changes, which are reflected in the energy and raw material consumption, can be saved.

To measure the concentration of the cleaner and the degree of contamination
in the bath continuously, accurately and quickly, the LiquiSonic® analyzer of SensoTech will be directly integrated into the process. The automatic real-time measurements every second show immediately how much cleaner must be replenished to keep the cleaning result constant.

For example,
the analyzer Is used in cleaning and degreasing baths, in rinsing baths, pickling and etching baths and coating and plating baths as well. Installing the  LiquiSonic® sensor into the plant is easy and suitable for every cleaning or surface processing plant. This eliminates time-consuming manual measurements, which provide delayed and often inaccurate results by titration analysis.
In contrast, the LiquiSonic® technology measures inline and accurately in various bath fluids, because the measuring method is independent of the turbidity and conductivity of the fluid and has a high tolerance of soiling.

Via fieldbus, analog outputs, serial ports or Ethernet,
the measuring data can be transmitted to control systems, so that an automatic, targeted cleaner dosage is guaranteed. For process transparency and traceability, the measuring data are continuously recorded and stored in LiquiSonic® controller. Clear trend charts and custom data protocols provide a comprehensive overview of the process flow.

 

Directly in the bath
the LiquiSonic® analyzer of SensoTech measures quickly and accurately the cleaner concentration and degree of contamination
