Diaphragm seal systems protect gauges from hot, viscous, contaminated or corrosive media. This added layer of protection ensures that the media doesn't reach the gauge, helping to prevent gauge failure that can cause safety issues for operations and personnel. Diaphragm Seals

Flanged. Flanged diaphragm seals allow direct mounting on pipes, tanks, and standardized flange connections. Typically, they are mounted to pressure gauges and switches directly, or with the use of a flexible capillary. As with all seals, the flanged option should be selected based on process compatibility.

Founded in 1904, USG's product offering includes bourdon tube and diaphragm capsule pressure gauges ranging in size from 1-1/2 inches to 6 inches; with brass, stainless steel, or Monel internals. Other products include a complete line of diaphragm seals, a full range of bimetallic thermometers from 1 inch to 5 inches in diameter, and thermowells.

A typical Diaphragm pressure gauge contains a capsule divided by a diaphragm, as shown in the schematic . One side of the diaphragm is open to the external targeted pressure, PExt, and the other side is connected to a known pressure, PRef,. The pressure difference, PExt - PRef, mechanically deflects the diaphragm. 6. • The membrane deflection ...

Diaphragm Seals, also known as Chemical Seals or Gauge Isolators, are built to protect pressure measurement instrumentation from process fluid that is hot, clogging, corrosive, sanitary, or otherwise threatening to the instrument. One of the most important aspects in selecting a long-lasting diaphragm seal is choosing the diaphragm foil material.
