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

摘要： A multivariable process fluid pressure transmitter includes an electronics module and a sensor module. The sensor module is coupled to the electronics module. A process fluid temperature sensor is coupled to the process fluid pressure transmitter. A differential pressure sensor is disposed within the sensor module and is operably coupled to a plurality of process fluid pressure inlets. A static pressure sensor is also disposed within the sensor module and is operably coupled to at least one of the process fluid pressure inlets. A first temperature sensor is disposed within the sensor module and is configured to provide an indication of a temperature of the differential pressure sensor. A second temperature sensor is disposed within the sensor module and is configured to provide an indication of a temperature of the static pressure sensor. Measurement circuitry is operably coupled to the differential pressure sensor, the static pressure sensor, and the first and second temperature sensors. A processor is coupled to the measurement circuitry and is configured to provide a compensated differential pressure output based on a measurement of the differential pressure sensor and the first temperature sensor, and to provide a compensated static pressure output based on a measurement of the static pressure sensor and the second temperature sensor.

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

摘要： A process instrument mount includes an outer wall and an inner wall. The outer wall is separated from the inner wall by a space. The mount has a first end and a second end, and a hole extends from the first end to the second end. The inner wall surrounds the hole, and has a threaded region to receive a process instrument from the first end. The inner wall also has a flange proximate the second end to sealingly mate with the process instrument. In one embodiment the inner and outer walls are portions of a unitary metal block, and the space separating them comprises a groove formed in the metal. In another embodiment the inner and outer walls are separate parts joined together at the second end and spaced apart between the first and second ends.
