A single-use adapter for coupling a single-use container to a reusable sensor transducer includes an attachment region. The single-use adapter includes a deflectable diaphragm sealingly coupling to the attachment region and configured to contact a media sample. The single-use adapter also includes a radio-frequency identification (RFID) tag coupled to the single-use adapter and configured to store and transmit data.

Single-use pressure transducer disposable interface

A transmitter for measuring a process pressure includes a pressure sensor and a temperature sensor providing an input temperature signal. A first remote pressure sensitive diaphragm couples to the transmitter by a first capillary tube filled with a fill fluid having a density as a function of fill fluid temperature. An input circuit is operably connected to at least the pressure sensor and provides an intermediate pressure signal at least roughly representative of the process pressure. A correcting circuit is coupled to the temperature sensor and to the input circuit. The correcting circuit processes the intermediate pressure signal by compensating for the fill fluid density as a function of the temperature and provides a compensated output more closely representative of the process pressure. The correction circuit further performs an initial height determination based upon a pressure measurement made while no pressure is applied to the first diaphragm.
