摘要： A pressure measurement system includes a co-planar pressure sensor module (200) coupled to a bi-planar pressure flange (202; 502). The co- planar pressure sensor module (200) has a pair of isolator diaphragms that are substantially co-planar with one another. A plurality of connection rings (204; 206; 504; 506) are welded proximate and about respective isolator diaphragms. A bi-planar pressure flange (202; 502) is welded to each of the connection rings (204; 206; 504; 506). Fluidic coupling from a process fluid pressure inlet of the bi-planar flange (202; 502) to an isolator diaphragm of the co-planar pressure module (200) occurs without encountering any compressive seals. A method (400) of manufacturing a pressure measurement system is also provided.

摘要： A multivariable process fluid pressure transmitter (10) includes an electronics module (18) and a sensor module (222). The sensor module (222) is coupled to the electronics module (18). A process fluid temperature sensor is coupled to the process fluid pressure transmitter. A differential pressure sensor (228) is disposed within the sensor module (22) and is operably coupled to a plurality of process fluid pressure inlets. A static pressure sensor (230) is also disposed within the sensor module (222) and is operably coupled to at least one of the process fluid pressure inlets. A first temperature sensor (232) is disposed within the sensor module (222) and is configured to provide an indication of a temperature of the differential pressure sensor (228). A second temperature sensor (234) is disposed within the sensor module (222) and is configured to provide an indication of a temperature of the static pressure sensor (230). Measurement circuitry (328) is operably coupled to the differential pressure sensor (228), the static pressure sensor (230), and the first (232) and second (234) temperature sensors. A processor (326) is coupled to the measurement circuitry (328) and is configured to provide a compensated differential pressure output based on a measurement of the differential pressure sensor (238) and the first temperature sensor (232), and to provide a compensated static pressure output based on a measurement of the static pressure sensor (230) and the second temperature sensor (234).

摘要： An in-line pressure transmitter (10) for sensing an absolute or gage process pressure of a process fluid includes an in-line process coupling (14). The coupling has a mounting member (16) which includes a substantially flat mounting face (18) and a bore generally aligned with an isolation diaphragm assembly (30). The member (16) is configured to mount to a flat process coupling.

摘要： A manifold (10) includes a body having generally planar inlet surface (14). The inlet surface (14) includes a first inlet (16) and a second inlet (18) adapted for coupling to a pressurized process fluid. An outlet surface (22) on the manifold (10) is adapted for coupling to a co-planar transmitter and is at angle relative to the inlet surface (14). The manifold (10) includes an equalizing valve surface (24) opposite the outlet surface (22), and a perimeter therebetween. The outlet surface (22) includes first and second outlets (26, 28) in fluid communication with the first and second inlets (16, 18), respectively.
