Abstract: An in-line process fluid pressure transmitter is provided. The transmitter includes a process fluid connector configured to couple to a source of process fluid. A plug is coupled to the process fluid connector and has a passageway configured to convey fluid to a distal end of the plug. A pressure sensor subassembly is coupled to the plug at a weld. The pressure sensor subassembly has a pressure sensor operably coupled to the distal end of the passageway such that the pressure sensor reacts to process fluid pressure. The plug includes a sidewall encircling the weld. Transmitter electronics are coupled to the pressure sensor and configured to measure an electrical characteristic of the pressure sensor and provide a process fluid pressure value based on the measured electrical characteristic.
