Overview
The Omega PX359-030G5V is an all-stainless-steel 0-30 psi gage pressure transducer from the PX309 general-purpose series, delivering ±0.25% BSL static accuracy in a rugged, solid-state design. This range uses oil-filled stainless diaphragm for stable, low-drift performance. It outputs a 0-5 Vdc signal, carries an IP65 protection rating, and ships with a 5-point NIST-traceable calibration certificate. The PX309 is multimedia-compatible for use with a wide range of liquids and gases.
Best for
- General-purpose industrial pressure measurement on a budget without sacrificing stainless durability
- OEM equipment, hydraulics, pumps, compressors, and process monitoring
- 0-5 Vdc input PLCs, data loggers, and panel meters
- Multimedia applications across compatible liquids and gases
Warranty
Backed by Omega's standard 13-month warranty (1-year coverage plus a one-month shipping grace period) against defects in materials and workmanship. ZOT Supply is an authorized Omega distributor offering fast nationwide and international shipping. Each unit ships with its 5-point NIST-traceable calibration certificate.
