Abstract: A pressure-sensing system is presented. The pressure-sensing system comprises a single-use container. The pressure-sensing system comprises a disposable process connector configured to couple directly to the single-use container. The disposable process connector has a deflectable diaphragm. The pressure-sensing system comprises a pressure transducer. The pressure transducer is removably coupled to the disposable process connector. The pressure transducer comprises an isolation diaphragm positioned adjacent the deflectable diaphragm of the disposable process connector. The pressure transducer comprises a pressure sensor module operably coupled to the isolation diaphragm. The pressure transducer also comprises a controller coupled to the pressure sensor. The controller is configured to transmit a detected indication of pressure within the single-use container. A pressure transducer for a single-use container includes a polymeric housing and a base having an isolation diaphragm. A sensor module is coupled to the base, and has a pressure sensor operably coupled to the isolation diaphragm. Circuitry is disposed within the polymeric housing and coupled to the pressure transducer. The circuitry includes a microprocessor configured to obtain a pressure measurement from the pressure sensor and provide an output signal based on the measured pressure.
