Document Type and Number:
Japanese Patent JP2002513148
Kind Code:
A
Abstract:
A process control instrument adapted to provide an output indicative of a parameter of a process fluid is disclosed. The process control instrument is designed to be attachable to a flange having a first passageway filled with process fluid. A body of the process control instrument has an opening adjacent to the first passageway adapted to receive process fluid from the first passageway. An isolation diaphragm is positioned in the opening of the body and separates the opening and the first passageway from a second passageway. A weld ring positioned in the opening is adapted to evenly distribute an attachment force across a support surface such that damage to the isolation diaphragm is minimized.
