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 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.

摘要: A scalable process transmitter architecture includes a unitized sensor module and an optional scalable transmitter. The sensor module has a sensor output that is configurable which can connect locally to a scalable transmitter module to form a transmitter, or can be wired directly to a remote receiver. The scalable transmitter can mount on the unitized sensor module and generates a scalable output for a remote receiver. The transmitter module can provide more advanced features for specific applications.

摘要: A field device is coupled to a process through at least one process interface element. The process interface element may be a field device flange, a manifold, or a process flange. The process interface element has a temperature sensor attached thereto, and is adapted to receive a thermal source. In one embodiment, the thermal source is one or more electrical heaters. In another embodiment, the thermal source is thermal transfer fluid tracing through the process interface element. A controller is coupled to the temperature sensor and is adapted to control the heat applied to the process interface element based upon the temperature of the process interface element measured by the temperature sensor.

摘要: A pressure transmitter with a hermetically sealed housing surrounding a cavity that is filled with a gas that is free of integrated circuit contaminants. A sensor circuit including an integrated circuit is placed in the cavity and a gas fill port on the housing is sealed. The sensor circuit is electrically adjustable from outside the pressure transmitter and the integrated circuit is protected from contaminated atmospheres outside the pressure transmitter.

摘要: 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.
