Overview
The Omega PX459-3.5KGI-XL is a high-accuracy 0 psi to 3500 psi gage pressure transducer built on Omega's micro-machined piezoresistive silicon platform, delivering best-in-class accuracy that combines linearity, hysteresis, and repeatability. A custom ASIC applies digital dynamic thermal compensation across the full temperature and pressure range, so the transducer holds its accuracy where lower-grade devices drift. It outputs a 4-20 mA signal and ships with a 5-point NIST-traceable calibration certificate.
Best for
- Aerospace, automotive, and test-bench measurement requiring reference-grade accuracy
- Industrial process and equipment OEM applications with wide ambient temperature swings
- 4-20 mA input PLCs, data loggers, and panel meters
- Rugged, all-stainless installations in harsh industrial environments
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
<0.1% Non-Linearity Class
Specified to a non-linearity accuracy class under 0.1%, delivering high-grade performance across the calibrated span.
Digital Thermal Compensation
A custom ASIC maps temperature, pressure, and output to dynamically compensate across the compensated range, holding span and zero where competitors drift.
