    Abstract: A process fluid pressure measurement system includes a process fluid pressure transmitter coupled to a coplanar manifold (120). The coplanar manifold (120) includes a first bore (112) coupleable to a source of process fluid, and a vent passageway (114) connected to the first bore and terminating in a vent hole (108). The coplanar manifold (120) includes at least one port (122) configured to receive a valve stem (52). Directly engaging the valve stem (52) with the coplanar manifold selectively vents the coplanar manifold. Aspects of the present invention also include a coplanar manifold for coupling fluid to a process fluid pressure transmitter, and a method of venting such a coplanar manifold.

    Abstract: A capacitive pressure transmitter (300) is provided. In one aspect, the transmitter (300) includes a capacitive pressure sensor (56) coupled directly to the measured media without any intervening fluid isolation. A filter is preferably used to keep particulates from reaching the measuring diaphragm. In another aspect, a capacitive pressure transmitter (300) is provided with at least one self-contained isolator (210) interposed between a process connection (200) and the capacitive pressure sensor (56). In both aspects, the capacitive pressure transmitter (300) is relatively small and preferably constructed from materials that facilitate low-cost manufacture. Silicon oxide is used as a plate coating.

    Abstract: A transmitter provides an output that is indicative of pressure and has two modular transmitter bodies (20, 30), one (20) including a sensor (22), and the other (30) having an isolator diaphragm (32, 33) with a substantially non-compressible fluid that transfers movement of the isolator diaphragm (32, 33) to the sensor (22). The bodies each have mating passageways (36, 37, 40, 41) to transfer non-compressible fluid from one body (30) to the other (20) and are assembled together using a ring of extrusile material (48, 49) disposed around the mating portions of the passageways to seal the passageways together when the transmitter bodies (20, 30) are assembled. The isolation fluid is filled in the passageways before the first and second transmitter bodies (20, 30) are assembled. The assembly can be accomplished without complex procedures and still insure that accurate transmitter operation will be obtained.
