1 Process Gauge IsolationDiaphragm Seals and Isolator RingsBy David Gardellin, President Onyx Valve CoPressure measurement on a compressed air or cooling water line is fairly straightforeword: simply tap a Gauge at some point in the line. Fluids such as air and water haveno adverse effects on the internal components of the Gauge . Other fluids, however, maynot be so benign. Many fluids subject to pressure measurement are corrosive, or theycontain solids, or they crystallize or fluids include strong acids and bases, adhesives, slurries, sewerage,sludge, pigments, food products such as cheese or ground meat, molten plastic and mineore these fluids, we have to isolate the Gauge from the Process fluid with a barrier thattransmits pressure while isolating the Gauge from direct contact with the fluid beingmeasured.
