- Wide range of electrical connections available
Categories: Barksdale, Pressure, Pressure Transducer
Barksdale's Series 420 and 422 Transducers are general purpose, industrial grade transducers, ideal for use in general industrial applications. Wetted parts are constructed of 17-4PH and 300 Series Stainless Steel, with NEMA 3 enclosures constructed of 304 Stainless Steel. These units use a stable, diffused silicon sensor, that achieve .25% accuracy, have pressure ranges from 0-10,000 psi and are available with either 0 - 30 millivolt or 0 - 100 millivolt ratiometric output. High pressure snubbers are standard on units at 2,000 psi and above.
