OMEGA’s PX81 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 temperature-compensation error minimizes errors due to changing process temperatures, and the rugged all stainless steel construction allows the PX81 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 Series transducers will interface with most control systems.
The PX81 is also available in metric configurations, with G1/4 ports, and models from 0-350 mbar to 0-35 bar pressure ranges. Please see the PXM81 for complete details, or contact our Pressure department for more information..
