Abstract
A transmitter provides an output indicative of pressure of process fluid. The transmitter has a first body with a passageway filled with isolation fluid extending from a first port to a pressure sensor. A second body has an inlet for receiving process fluid and a second port. An isolation diaphragm between the first and second ports isolates process fluid from isolation fluid. A seal adjacent the diaphragm seals the diaphragm and couples the diaphragm to the second body. A spring urges the seal against the diaphragm.
