Measurement of cavitation in ultrasound
Characterization and control of cleaning processes
Ultrasonic cleaning is based on cavitation, a physical phenomenon that is essential for effectively removing contamination. However, the mere presence of ultrasound does not by itself guarantee that the cleaning process is truly effective.
At BIDEA, we offer objective verification of ultrasonic cleaning equipment and lines through cavitation measurement using specialized measurement system.
Our technology records the acoustic noise generated by the implosion of cavitation bubbles, a parameter that directly correlates with the actual cleaning effect. The method provides a numerical, quantifiable, reproducible, and documentable result, overcoming the limitations of traditional methods such as aluminum foil tests or color indicators.
Application and objective
Cavitation measurement is applied in ultrasonic cleaning processes where it is necessary to verify that the equipment operates with the appropriate intensity and uniformity to ensure effective cleaning. Its objective is to assess the actual performance of the system, detect possible variations between units or within different areas of the tank, and ensure that operating conditions provide the level of cavitation required to achieve repeatable and consistent results.
On-site testing
We perform on-site inspections independently of the manufacturer and provide a technical report that documents the state of the process in terms of cleaning efficiency and cavitation level, facilitating system optimization and data-driven decision-making.
Technical and Operational Contribution
Cavitation verification provides direct value to the ultrasonic cleaning process. It allows for confirming the actual performance of the equipment, detecting areas with low acoustic activity, and optimizing operating parameters to improve cleaning effectiveness. Additionally, it delivers objective data that support decision-making, help standardize processes, and ensure repeatable and consistent results across any production line.
