High Accuracy, Sanitary Pressure Transducers

The PX409S Series sanitary pressure transducers and sanitary pressure transmitters are made using our proven micromachined silicon process. They are available with 1½ or 2 in sanitary fittings and are designed for long reliable service in pressure or level CIP applications in food processing, beverage or bio/ pharmaceutical applications as well as industrial applications that require a rugged, high accuracy transducer. The micro-machined silicon sensor provides a very stable transducer with exceptional high accuracy of 0.08% and a broad compensated range of -4 to 85°C (25 to 185°F). The modular construction allows for fast delivery of most configurations and fittings. Vacuum models measure negitive gage pressure, output is zero at ambient pressure and increases with decreasing pressure. Compound Gage models measure +/- gage pressure and have a corresponding bi-directional voltage outputs. 4-20 mA models have zero pressure (ambient) set at 12 mA. The OMEGA PX409S Series has been issued 3-A symbol authorization and meets the requirements of the 3-A Sanitary Standards.
