HOW THE PRODUCT WORKS
Continuous hydrogen purity analysis for hydrogen-cooled generator sets
Online hydrogen purity monitoring for hydrogen-cooled generators
The RS-301ON Hydrogen Purity Analyzer is designed for hydrogen-cooled generator sets. It determines gas content using the thermal conductivity principle, with a temperature-compensated thermal-conductivity cell intended to support stable, accurate monitoring as operating temperature varies.
Sampling system designed for continuous operation
The analyzer is supplied with a hydrogen sampling system that filters oil and moisture from the sample gas to help protect the transmitter during continuous monitoring. The product information also describes a precise sampling arrangement for on-site calibration, automatic drainage, and a safety bypass function. These features support routine operation and service access in generator applications.
Measurement ranges for generator gas mixtures
The published ranges cover CO₂ in air from 0–100%, CO₂ in H₂ from 0–100%, and H₂ in air from 90–100%. The factory 4–20 mA output is configured for H₂ in air over 90–100%, with a maximum load of 800 Ω. Confirm the required gas-mixture mode and output mapping for your generator and gas-replacement procedure.
Plan the installation around sample conditions
The specified sample flow is 0.5 SCFH and the sampling pressure is up to 0.1 MPa. The analyzer accepts AC 90–265 V at 50 Hz, with 35 W power consumption. Its published explosion-protection marking is Ex d IIC T6 Gb. Confirm site classification, sample tubing, interfaces, and applicable certificates as part of project engineering.
For a quotation or configuration review, provide the generator model, gas mixture and measurement mode, sample pressure and flow, power supply, required outputs, installation area classification, and commissioning requirements. This helps configure an online hydrogen purity analyzer for hydrogen-cooled generator operation.
