Resumen:
Un instituto de investigación alemán ha desarrollado un nuevo método para medir la eficiencia y efecto de limpieza de baños ultrasónicos. A pesar del amplio campo de aplicación de los limpiadores ultrasónicos en numerosas tareas, actualmente no existe ningún método generalmente aceptado que permita el análisis cuantitativo del proceso de cavitación. El nuevo sistema de medida permite determinar mejor el efecto de limpieza y la eficacia de baños ultrasónicos. El instituto de investigación busca licenciatarios.

Tittle:
New method to measure the strength of cavitation
Summary:
A German research institute developed a new method to measure the efficiency and cleaning effect of ultrasonic baths. Despite the broad application of ultrasonic cleaners for manifold tasks, there are up to know no generally accepted methods that allow a quantitative assessment of the cavitation process. The new cavity thickness meter enables a significantly improved determination of the cleaning effect and the efficiency of ultrasonic baths. The research Institute is looking for licensees.
Description:
A German research institute, active in metrology, has developed a new method to determine the cleaning effect and the efficiency of ultrasonic baths. The new cavity thickness meter significantly improves the quantitative description of cavitation fields and can be used for the assessment of the efficiency of ultrasonic baths, sonochemical processes, cell occlusion or the production of emulsions.

To measure the quantity of cavitation the method operates with with two closely arranged acoustic sensors. One sensor is covered with a soft protective coating so that it only detects acoustic signals originating from blisters that are far from the surface to be cleaned. The other sensor is uncoated and receives signals that originate from cleaning-active blisters as well. By comparison with the measurement signal of the coated sensor, the noise signal of the active blisters can be determined separately.

The sensor principle can be implemented with various sensor forms. In particular, it is possible to use the sensors in typical components to be cleaned in order to determine the cleaning effect for a concrete element.
Advantages and Innovations:
The offered measurement system offers the following advantages:
- Easy and cost-effective sensor design.
- Distiction between cleaning-active and passive blisters.
- Quantitative signal that is directly linked to the near-surface cavitation.
Stage of Development:
Under development/lab tested
