Abstract: A method of manufacturing a pressure sensor for sensing a pressure of a process fluid includes obtaining a sensor body having a sensor cavity formed therein. A metal tube is placed through an opening in the sensor body into the sensor cavity. A rod is placed through the metal tube and into the sensor cavity. The sensor cavity is at least partially filled with a dielectric material and the dielectric material completely covers the metal tube carried in the sensor cavity and a portion of the rod. The rod is removed and thereby forming a dielectric passageway which is fluidically coupled to the metal tube. The sensor cavity is sealed with a deflectable diaphragm which is configured to deflect in response to applied pressure from the process fluid. A differential pressure sensor for sensing a differential pressure of a process fluid includes a sensor body having a sensor cavity formed therein is also provided.

Abstract: A pressure transmitter system for measuring a pressure of a process fluid in an industrial process includes a pressure transmitter having a pressure sensor. A process fluid passageway having a circular opening is configured to couple pressure of the process fluid to the pressure sensor. A concentric seal support structure extends around the circular opening comprising an annular recess. An annular stress riser is positioned radially inward from the annular recess. A seal material fills the annular recess and contacts at least a portion of the annular stress riser.
