Depending on the cleanliness requirements, it is possible to achieve clean parts and surfaces with less or high efforts. But regardless of whether the cleaning process is running simple or challenging, the efficiency of the process is always relevant.
This includes the relation of input and output. That means for the parts and surface cleaning to minimise resources with meeting the cleanliness requirements. Control variables are, amongst others, the cleaner or a change of the bath.
Apart from using a cleaner according to the requirements, efficient cleaner adding is very important for the bath reconditioning and maintenance. Over- or underdosage should be avoided for cost and quality reasons.
Continuous accumulation of remaining liquids in cleaning and rinsing baths reduces the product quality, so that the baths have to be reconditioned regularly. However, the frequency of bath changes should be efficient. On the one hand, if a bath is changed too early, it will cause an over-consumption for cleaners, energy, fresh water and wastewater. On the other hand, if a bath is changed too late, the quality will be reduced.
In order to run the cleaning process reliably and economically, it is recommended to use the inline analyser “LiquiSonic®“ manufactured by SensoTech. The sensor of the system measures the cleaner concentration permanently and directly in the process, so that the values won’t fall below or exceed predefined limits. When using the LiquiSonic® system, it enables control of the change of rinsing baths in a targeted way. Therefore, bath changes passed too early or too late will be excluded.
The concentration measurement is based on the sonic velocity measurement providing fast and precise measured values. The LiquiSonic® sensor works maintenance-free and is completely made of stainless steel.
The controller of the system manages and visualises the measuring data. With connection to process control systems, it allows integration of the process control into the automatic control.
