Robust two piece design
The diaphragm is welded to the body to ensure separation of the filling fluid from the process medium
All SS construction

Diaphragm seals are designed to isolate the sensing element of pressure gauges and pressure switches from process fluids that they may be corrosive, viscous, sedimentous and / or with a high temperature.
