The 425T4-25 is a Pressure Transducer for Barksdale Products application.  The transducer can receive a pressure range within 0-5 PSI.

425 Transmitters are general purpose, industrial grade transducers, ideal for use in general industrial applications when a robust transducer is required. Wetted parts are constructed of 17-4PH and 300 Series Stainless Steel, with NEMA 4 enclosures constructed of 304 Stainless Steel. These units feature a stable, diffused silicon sensor, that achieves .25% accuracy, have pressure ranges from 0-10,000 psi and are available in 5V, 10V or 4-20MA outputs. High pressure snubbers are standard on units at 2,000 psi and above. Optional surge voltage protection to 6kV is available.
