introduction to diaphragm seals MGS9
04-Diaphragm-Seals 2

The diaphragm seal is designed to measure the process fluid pressure when the process fluid temperature is non-compatible to the
instrument sensing element; when the process fluid may corrode the inner parts of the measuring instrument in contact with the fluid;
when the fluid is highly viscous or it contains solid suspensions; when it solidifies at temperature changes.
It is also used for long-distance pressure fluid transmission and measurement allowing to isolate dangerous fluids from the operating
areas. It can be directly connected to the indicating instrument or through a capillary.
