A media isolated pressure sensor  uses an inert silicon oil as the transfer fluid when pressure is applied to the corrugated diaphragm.  The design isolates the corrosive gas or liquid from the MEMS sense element and allows for a variety of process connectors.   The hermetic welded design and minimal oil volumes produce a sensor that is low in thermal errors and extremely linear with pressure with ranges from 2psi to 3000psi in gage, vacuum, absolute and sealed gage configurations.
