Series 423, 425, 426

Description

Barksdale's Series 423 and 426 Transducers and 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 4-20 mA outputs. High pressure snubbers are standard on units at 2,000 psi and above. Optional surge voltage protection to 6kV is available. A variety of process fittings and electrical connections are available to meet your needs.
