<p>A process pressure measurement system is provided. The system includes a remote seal assembly (12) configured to couple to a process and having a remote seal diaphragm (26) that has a first side adapted to contact a process fluid (20) and a second side adapted to contact a substantially incompressible fill fluid. A first capillary conduit (16) is coupled to the remote seal (12) and is filled with the substantially incompressible fill fluid. A first coupling (38A) is coupled to the first capillary conduit (16). A process fluid pressure transmitter (14) having a pressure sensor (32) is operably coupled to a pressure inlet. A second capillary conduit (16) is coupled to the process fluid pressure transmitter (14). The second capillary conduit (16) is filled with the substantially incompressible fill fluid. A second coupling (38B) is coupled to the second capillary conduit (16) and to the first coupling (38A) to provide fluidic communication from the remote seal diaphragm (12) to the pressure inlet of the process fluid pressure transmitter (14). At least one of the first and second couplings (38A 38B) is sized to pass through a penetration (42) in a process containment barrier (40). A method of joining two closed fluid systems for process pressure measurement is provided. A remote process seal assembly (12) is also provided.</p> |
