  • Method and evaluator for determining the state of a degassing device
    Patent number: 10538102
    Abstract: A degassing device can include one or more passive components, such as a gas-permeable membrane. The passive components may not directly be monitored. The state (e.g. the permeability) of the passive components may be reliably determined via evaluation of pressure information with regard to the pressure (e.g. negative pressure) in the degassing device.
    Type: Grant
