Seal for pressure transmitter for use in industrial process

摘要

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.
