Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.
Pressure in Carbonated Beverages
In beverages such as beer and sodas and even water, pressure makes them better. In some cases, without the pressure, due to aging or simply leaving the container’s contents exposed to air, the beverage goes flat and is undrinkable.
The sugar content of homemade beer can create pressure differences from 36 psi for a high sugar content to 30 psi for half of that level. Commercial beers typically have carbonation that creates pressures up to 45 psi. Carbonated soft drinks typically have pressures from 30 to 50 psi. The actual pressure for a specific container/content combination can vary based on temperature, altitude and shaking.

While a pressure sensor on a bottle or can does not make any sense, commercial suppliers and even home brewers need to know what levels to expect so they can package their bubbly beverage in a safe container. In a production process, monitoring pressure of the carbonation source and sampling bottle/can pressures can also ensure consistent quality of the end product. In either case, pressure measurements provide valuable information.
