Overview
The Omega PX359-V050GI is an all-stainless-steel -15 to 50 psi compound gauge pressure transducer from the PX309 general-purpose series, delivering ±0.5% BSL static accuracy in a rugged, solid-state design. This range uses oil-filled stainless diaphragm for stable, low-drift performance. It outputs a 4-20 mA 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
- 4-20 mA 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.
Key Features
±0.5% BSL Accuracy
Combined linearity, hysteresis, and repeatability for this unit, verified with a 5-point NIST-traceable calibration certificate.
All-Stainless Construction
316 stainless steel build with 316 SS wetted parts for broad multimedia compatibility and long service life.
Oil-Filled Sensing Diaphragm
A high-accuracy silicon sensor protected by an oil-filled stainless diaphragm provides sensitive, stable measurement at this pressure range.
Bidirectional Compound Range
Measures both vacuum and positive pressure across its -15 to 50 psi compound range from a single port.
IP65 Protection
Sealed to IP65 for dusty and washdown-adjacent industrial environments.
4-20 mA Loop Output
Provides a 4-20 mA current-loop output with reverse-polarity and over-voltage protection for long-run, noise-immune signaling.
