OMEGA’s PX91 is a rugged,
ultra-high pressure transducer
series. Hermetically sealed, with
all stainless steel construction, it is
designed for use in test chambers.
The PX91 is available in sealed
gage pressures up to 200,000 psi.
It has a high operating temperature
up to 204°C (400°F). The pressure
connection is via a high-pressure
ferrule connection.
