ABSTRACT:
A pressure-sensing module includes a housing having a process-fluid port configured to be coupled to a process-fluid-flow circuit. The housing defines a first chamber into which the process fluid can flow through the process-fluid port. An isolator assembly is disposed within the housing and includes a fill port. The isolator assembly is configured to define a second chamber into which pressure-coupling fluid may be injected through the fill port. An electronic circuit is disposed within the second chamber and is configured to be pressure coupled by the coupling fluid and isolator assembly to the flow circuit. A plug having first and second ends occupies the fill port thereby sealing the second chamber. The first end is exposed to the process fluid in the first chamber, and the second end is exposed to the coupling fluid in the second chamber.
