  • Pressure indicator
    Patent number: 6799467
    Abstract: Pressure is measured inside of a high pressure vehicle. A substance is compressed at a first pressure to create a preform having a first density. The preform is placed inside of a high pressure vessel and subjected to a second pressure, greater than the first pressure. The preform therefore changes in density to a second density, greater than the first density, whereby the second pressure can be determined. The method may also be used in determining the pressure inside of a food product during food processing and a high pressure vessel.
