OMEGA’s PX81/PXM81 Series wet/
wet, differential pressure transducers
are compact and highly accurate,
designed for industrial applications in
which low drift and long-term reliability
are important. Their small temperaturecompensation error minimizes errors
due to changing process temperatures,
and the rugged all stainless steel
construction allows the PX81/PXM81 to
withstand typical harsh environments
found in chemical and industrial plants.
Available with either mV/V, 0 to 5 Vdc,
or 4 to 20 mA outputs, PX81/PXM81
Series transducers will interface with
most control systems.
