Embodiments of the present disclosure are directed to field device housing assemblies and field devices that include the housing assemblies. One embodiment of the field device housing assembly includes a main housing, a cover having a proximal end connected to the main housing, a transparent panel and a retainer ring. An interior wall of the cover includes a threaded section that is concentric to a central axis, and a flange extending radially inward from the interior wall toward the central axis. The transparent panel is received within a socket defined by the interior wall and the flange. The retainer ring is secured to the threaded section of the interior wall. The transparent panel is clamped between the retainer ring and the flange.

Field device housing assembly

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.

Temperature compensation of a multivariable pressure transmitter

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.

Bi-planar process fluid pressure measurement system

A remote seal assembly includes a seal body and an extension. The seal body defines a cavity with a diaphragm that seals the cavity from a process fluid. The extension is connected with the seal body on a first end and is configured for connection to a capillary tube on a second end. The extension defines a bore extending from the first end to the second end that is fluidically coupled to the cavity. A length of the extension is related to a temperature of the second end of the extension such that the second end of the extension is at or below an outgassing temperature of the material used to connect the extension and the capillary tube.

Capillary weld extension with thermal isolation

A manifold includes a body having generally planar inlet surface. The inlet surface includes a first inlet and a second inlet adapted for coupling to a pressurized process fluid. An outlet surface on the manifold is adapted for coupling to a co-planar transmitter and is at angle relative to the inlet surface. The manifold includes an equalizing valve surface opposite the outlet surface, and a perimeter therebetween. The outlet surface includes first and second outlets in fluid communication with the first and second inlets, respectively.

Manifold for use with a pressure transmitter

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.

Process connection for in-line pressure transmitter

An environmentally sealed instrument circuit adapter connecting a process transmitter to instrument wiring. An environmentally sealing elastomeric part seals between a lip on an outer sleeve and a connector header of the process transmitter. One or more washers can provide sealing between the lip and the elastomeric part when tightened. The adapter protects contact pins, sockets and loop wires from damage due to liquids, humidity, dust and other contaminants.

Environmentally sealed instrument loop adapter

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.
