Beschreibung
Zusammenfassung:	A process fluid pressure transmitter (10) includes a sensor body (14) having a pressure sensor (16) and electronics (18) coupled to the pressure sensor (16) to obtain an indication of pressure from the pressure sensor (16). At least one process fluid isolation assembly is fluidically coupled to the pressure sensor and is configured to receive a process fluid. The process fluid isolation assembly includes an isolation diaphragm (58) welded to a weld ring (70, 80). The weld ring (70, 80) has a sealing surface on a first side adapted for contact with a metal sealing ring (72) and a weld portion welded to the sensor body (14) on a second side. The sealing surface and the weld are substantially aligned with one another.
