Zusammenfassung:	A pressure transmitter (10) includes an isolator mounting assembly (12, 150) for isolating process fluid from an interior cavity (22) of the pressure transmitter (10). The isolator mounting assembly (12, 150) includes an isolator plug (66, 152) for receiving the process fluid line pressure and coupling the line pressure to a sensor cavity (32) formed by a header (68, 154) joined to a distal end of the plug (66, 152). A ring member (70) is attached to the header (68, 154) and the distal end of the plug (66, 152) to reinforce the joint formed between the isolator plug (66, 152) and the header (68, 154). In another embodiment, the isolator mounting assembly (150) includes a base (154) and a support (181) having first and second opposed ends (190, 202). The first end (190) is rigidly bonded to the pressure sensor (184) while an epoxy joint (200) joins the second end (202) of the support (181) to the base (154).
