Intelligent update for the Libelle Cleaner Control
A further development in the field of sensor technology promises improved control of the cleaning media used and therefore more precise dosing and greater process reliability. The Fraunhofer Institute for Manufacturing Engineering and Automation IPA was commissioned to check this information and has now confirmed the function and accuracy of the existing measuring equipment. With this latest technical update, Libelle Cleaner Control from BvL Oberflächentechnik GmbH aims to set new standards in the reliability of monitoring and controlling industrial cleaning processes.
Precise monitoring and control of the cleaner concentration
Continuous monitoring and exact dosing of the cleaning chemicals is of central importance in component cleaning. Reproducible and high-quality cleaning results can only be achieved if the concentration and composition of the cleaning medium are kept within the optimum range. At the same time, precise dosing helps to minimize the consumption of cleaning media, which has both economic and ecological benefits.
This is particularly challenging under difficult operating conditions. In many real production environments, the cleaning baths are exposed to dynamic interference: oil residues, particles carried in, air inclusions, flow turbulence or changing temperatures influence the composition of the medium and make reliable inline measurement difficult. Conventional sensor systems can deliver inaccurate or fluctuating measured values under such conditions - with direct consequences: Overdosing leads to unnecessary consumption as well as increased costs, while underdosing impairs the cleaning effect. Both can cause subsequent problems in downstream processes.
Such uncertainties are unacceptable, especially in sensitive applications, such as in the automotive and aerospace industries, where the cleanliness of components is even relevant to safety. Precise, robust and process-reliable sensor technology is becoming a key technology here in order to guarantee both cleaning quality and resource efficiency in the long term.
Improved sensor technology as the key to success
For this reason, BvL Oberflächentechnik GmbH has focused its development efforts on sensor technology. Thanks to this further development, the Libelle Cleaner Control now delivers more stable and reproducible measurement results, even under difficult conditions. The cleaning medium can now be dosed and analyzed more precisely, which in turn reduces consumption, increases efficiency and, above all, improves process reliability. This is made possible by two decisive technical improvements: the introduction of upright measurement instead of measurement according to the flow principle and an integrated cleaning function for removing deposits from the sensor at regular intervals - reliably and without manual intervention.
Both functions have been submitted for patent application and are now an integral part of the BvL Libelle Cleaner Control. The Fraunhofer Institute for Manufacturing Engineering and Automation IPA was commissioned as an independent testing institute to confirm the results. As part of comprehensive tests, the institute tested the three Libelle products - Fluid Control, Oil Control and Cleaner Control - and was able to confirm their function. The conclusion of the test report was that the systems perform as specified. This enabled added value to be created for industrial applications through practical further development.
