Device for non-destructive determination of internal pressure in beer cans based on acoustic resonance frequency measurement

Original language description

Microbiological contamination of beer often leads to the formation of carbon dioxide and consequently to an increase in internal pressure in sealed containers. Excessive pressure poses safety risks and may result in the destruction of the package. We developed and characterized a non-destructive device that determines internal pressure in beer cans by measuring their acoustic resonant frequencies. The method is based on exciting the can with a mechanicalimpulse and recording the resulting vibrational response with a microphone. The dominant resonant frequencies shift to higher values as internal pressure increases. Experiments performed on cans with defined CO₂ concentrations and temperatures demonstrated a linear relationship between resonant frequency and internal pressure over a wide range. The device achieves high repeatability and resolution and allows rapid, non-destructive monitoring of pressurechanges in sealed cans. This makes the technique suitable for storage studies and for detecting pressure increases associated with microbiological spoilage.
