Series 423N1, 425N1, 426N1
Description
Barksdale's Series 423N1, 426N1 Transducers and 425N1 Transmitters are general purpose, industrial grade transducers, housed in junction boxes ideal for use in general industrial applications requiring protection from the environment. Wetted parts are constructed of 17-4PH and 300 Series Stainless Steel, with NEMA 4 enclosures constructed of die-cast aluminum. These units feature a stable, diffused silicon sensor, for up to .25% accuracy, have pressure ranges from 0-10,000 psi, and integral 1/2" NPT female conduit connections 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. These units feature field adjustable zero and span adjustment for fine tuning.
Features
- Diffused silicon sensor for high accuracy and reliability
- NEMA 4 J-Box for industrial use
- Field-adjustable zero and span output
- Stainless steel wetted parts
- Current and voltage signals
