OMEGA’s PX91 Series is a rugged, high pressure transducer for measurement of pressure at high temperatures. It is hermetically sealed, has all stainless steel construction and is designed for use in very high temperature test chambers. The PX91 is available in sealed gauge pressures up to 200,000 psi and operating temperature up to 218°C (425°F). The pressure connection is via a high pressure ferrule connection. FM approved intrinsically safe is standard.
