OMEGA’s PX91 amplified output
series comprises rugged,
high-temperature/ultra highpressure transducers. They
are hermetically sealed, with all
stainless steel construction, and
are designed for the harshest test
chamber environments. The
PX91 is available in sealed gage
pressures from 5000 psi to
200,000 psi. The electrical
connection is a lightning-protected
amplifier housing. The pressure
connection is via a highpressure ferrule.
