1. pressure transmitter assembly that is used for the pressure of measuring process fluid comprises:

  • The barrier film assembly, described barrier film assembly comprises barrier film, described barrier film is configured to be connected to process fluid and define the separate cavities relative with the procedural interface side along the procedural interface side;

    Pressure transducer, described pressure transducer is connected to the barrier film assembly, and spaced apart with described barrier film assemblies physical, with provide with the barrier film assembly near the heat of process fluid isolate;

    Extend to the conduit of pressure transducer from the separate cavities that is limited by barrier film, described catheter configurations is isolated fill fluid for carrying, thereby the pressure that will be applied to described barrier film is sent to described pressure transducer;

    WithTransmitter module is connected to the transmitter support of barrier film assembly;

    Wherein;

    described transmitter support has low relatively pyroconductivity;

    Also comprise;

    be used to compensate because the temperature sensor that the pressure survey that temperature variation causes changes.
