The well proven core sensor is an integrated silicon strain gauge bridge, encapsulated within a stainless steel case with a welded, isolating diaphragm (for a more detailed description, see data sheet Series 10). A G 1/4" male pressure port is welded as standard to give the very best in media compatibility and integrity - no "O"-rings or silicon are in contact with the media at all.  Pressure ranges: 200 mbar to 100 bar Օ Absolute, vented gauge or sealed gauge references  All 316 L stainless steel welded pressure cavity Օ Diameter 19 mm Standard Pressure Ranges (other ranges on request) PR 27 W: Vented Gauge.
