HOW THE PRODUCT WORKS
Online oxygen measurement for hydrogen stations and industrial process gas
Continuous oxygen monitoring in hydrogen streams
The RA1630 Online Oxygen-in-Hydrogen Analyzer is designed to measure oxygen content in hydrogen production stations, power plants, and industrial process gas. It uses an electrochemical oxygen sensor and an intrinsically safe probe to provide online measurement for applications where oxygen concentration in a hydrogen stream needs to be monitored.
Measurement and signal functions
The specified measuring range is 0–2% O₂, with ±0.03% accuracy, ±0.01% repeatability, and a 20-second response time. The analyzer provides a 4–20 mA analog output and two independently programmable alarm outputs. This allows measurement and alarm signals to be connected to a plant monitoring or control system; confirm the required scaling and alarm setpoints for your process.
Sampling and installation arrangement
The control unit is panel-mounted in a cabinet, with a specified cutout of 92 × 92 mm. The sampling system is wall-mounted on site and measures 600 × 450 × 120 mm. Product information describes a special acid/base pretreatment sampling system for complex samples. Review the actual sample chemistry and pretreatment requirements before specifying the installation.
Review site protection and operating conditions
The published operating temperature is −10 to +40 °C, enclosure protection is NEMA 4X / IP66, and the explosion-protection marking is Ex ia IIC T6 Ga. Confirm the hazardous-area classification, certificate requirements, sample composition, and panel and wall mounting locations as part of project engineering.
For a technical review and quotation, share the hydrogen source, expected oxygen range, sample composition and corrosive components, sampling arrangement, alarm setpoints, output requirements, installation location, and quantity. This supports a suitable online oxygen-in-hydrogen analyzer configuration for station and process monitoring.
