<p>A transmitter (10) provides an output indicative of pressure of process fluid. The transmitter (10) has a first body (14) with a passageway (32) filled with isolation fluid extending from a first port to a pressure sensor (16). A second body (13) has an inlet for receiving process fluid (28) and a second port. An isolation diaphragm (46) between the first and second ports isolates process fluid from isolation fluid. A seal (48) adjacent the diaphragm (46) seals the diaphragm (46) and couples the diaphragm (46) to the second body (13). A spring (66, 68) urges the seal (48) against the diaphragm (46).</p> |
