Series 420, 422

Description

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.

 

Features

  • General purpose, industrial grade transducer
  • Diffused silicon sensor for high accuracy and reliability
  • Rugged stainless steel construction
  • Built-in pressure snubber for high pressure applications (2000 psi and above)
  • Wide range of electrical connections available
