Gold Plated remote seal diaphragms designed for Hydrogen Process
Diaphragm seal systems offer protection to pressure transmitters, but some process fluids and aggressive chemicals can affect instrument integrity, leading to failure or even complete instrument replacement. Hydrogen is a molecule that can permeate metal by diffusing into the surface. For a pressure transmitters thin metal diaphragm this can lead to a loss in ductile and tensile strength, or introduce Hydrogen bubbles into the internal fill fluid. Adhering a thin layer of gold to a base metal provides protection against hydrogen permeation, extending the life of instrumentation and protecting your investment.
