Sealed Diaphragm Gauges operate on the principle of fluid transmission. The diaphragm which is the sensing element transmits the pressure through a system fill fluid typically Silicon Oil which in turn gives the bourdon tube a displacement. These gauges are ideal for viscous, corrosive media.
The gauges are available in both thread end and flange end connections.
