Abstract: A pressure transmitter with a fluid isolator that includes a sensor tube and a fill tube that have "D" shaped ends that connect together in a port internal to the transmitter. The shaped ends can be brazed into the port for sealing. Fitting both the sensor tube and the fill tube in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator has an isolator diaphragm with a central diaphragm region overlying a central backing plate that includes a annular groove. The annular groove avoids slow response of the isolator after an overpressure condition.

Abstract: A process control instrument (10) adapted to provide an output indicative of a parameter of a process fluid is disclosed. The process control instrument is designed to be attachable to a flange (13) having a first passageway (24) filled with process fluid. A body (12) of the process control instrument has an opening (28) adjacent to the first passageway adapted to receive process fluid from the first passageway. An isolation diaphragm (46) is positioned in the opening of the body and separates the opening and the first passageway from a second passageway (32). A weld ring (48) positioned in the opening is provided with an acurate or curved transition surface between a contact surface (206) being positioned against the isolation diaphragm (46) and a neighbouring surface (207) so as to evenly distribute an attachment force across a support surface (49) such that damage to the isolation diaphragm is minimized.
