Diaphragm Seal Assemblies

Typical Gauge and Seal Assembly

A diaphragm seal, properly applied, accurately transmits process pressure seen by the diaphragm to the instrument. The instrument and instrument side of the diaphragm seal are liquid filled. Since the liquid is incompressible, the process pressure is hydraulically transmitted to the pressure sensitive element of the instrument. In diaphragm sealed systems it is necessary that no air or other gases, (free, or entrained) be present in the instrument fill fluid. The displacement capability of the diaphragm must exceed the displacement required by the instrument primary element.

We can assemble either your current instruments or new complete assemblies with a wide variety of liquid fill fluids, in a timely manner, and the results are guaranteed.
