Generalities
In many cases it is no possible to use a pressure gauges
directly on the process; in these cases it is necessary to place a system between the
pressurised fluid and the pressure gauge that can transmit the pressure to be measured to
the gauge keeping, the gauge isolated from the process fluid.
These systems are called "seals" formed by a flessible diaphragm clamped between
two rigid plates; one side of the diaphragm is in contact with the fluid of process while
the other one with a neutral liquid completely filling the sensing element og the gauges.
The distortion of the diaphragm caused by changes in the pressure of the process is then
transmitted to the filling liquid and therefore to the gauge.
Features
Coupling of the gauge
direct or through a capillary for a remote mounting(max. lenght 8 meters).
