  • Process venting feature for use in sensor applications with a process fluid barrier
    Patent number: 11371902
    Abstract: A pressure transmitter includes a housing and a pressure sensor having an electrical characteristic that varies with applied pressure. The pressure sensor is configured to generate a sensor signal indicative of process fluid pressure. A transmitter isolation diaphragm is configured to couple to a process barrier seal to convey pressure to the pressure sensor. A flange is coupled to the transmitter isolation diaphragm. The flange includes at least one gas pathway extending inwardly from an outer diameter of the transmitter isolation diaphragm. Electronics are coupled to the pressure sensor to receive the sensor signal and to generate an output indicative of the pressure.
    Type: Grant

  • Compact sensor connector for single-use fluid measurement
    Patent number: 10921204
    Abstract: A connector for coupling a single-use container to a measurement instrument includes a connector region having a cylindrical sidewall. The connector includes a deflectable diaphragm sealed to the connector region and configured to contact a media sample. A portion of the deflectable diaphragm lines an interior surface of at least a portion of the substantially cylindrical sidewall.
