    Abstract: A process control system (10) utilizes wireless transceivers to divorce the field devices (14, 30) from traditional wired network topologies. By providing field devices (14, 30) with wireless transceivers (22) and shared wireless transceivers (36) for adapting wired field devices (30), the field device network may be adapted to any number of network topologies without concern for additional wiring costs. Specifically, a power supply (18, 26) can be provided for each field device (14) or for groups of field devices, as needed. Thus, the entire network can receive power from a single power bus (32), without expensive power filtering. In addition, the network can be a hybrid in which part of the information is transmitted and received over wired lines and part is transmitted and received over wireless communications.

    Abstract: A pressure transmitter (100) comprises a metal wall (102) separating a process pressure chamber (104) from an electronics compartment (106). The metal wall (102) has a stepped bore (108) with a bore shelf (110) facing the process pressure chamber (104). A metal header (112) has a stepped outer rim (114) with a header shelf that contacts the bore shelf. The metal header (112) includes at least one electrical feedthrough (122,124) with a glass-to-metal seal (126,128) adjacent the stepped outer rim (114). A welded seal (130) seals the stepped outer rim to the stepped bore.

    Abstract: A pressure transmitter (10) with a fluid isolator (11) that includes a sensor tube (38) and a fill tube (50) that have "D" shaped ends (40, 54) that connect together in a port (18) internal to the transmitter (10). The shaped ends (40, 54) can be brazed into the port (18) for sealing. Fitting both the sensor tube (38) and the fill tube (50) in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator (11) has an isolator diaphragm (96) with a central diaphragm region (100) overlying a central backing plate (94) that includes an annular groove (111). The annular groove (111) avoids slow response of the isolator (11) after an overpressure condition.
