HOW THE PRODUCT WORKS
Multi-parameter hydrogen quality monitoring for generator cooling systems
Integrated hydrogen quality monitoring for hydrogen-cooled generators
The RS301ON-III H2 Quality Analyzer is designed to monitor hydrogen cooling systems on generator sets. It brings together online measurement of hydrogen purity, dew point humidity, oxygen, and residual hydrogen, with alarm output and 4–20 mA remote transmission. This multi-parameter view can help operations teams assess gas quality and maintenance conditions from one analyzer platform.
Four monitored gas-quality parameters
Purity measurement uses micro-thermal conductivity for H₂/air, CO₂/H₂, and CO₂/air mixtures. Humidity dew point is measured by a resistance-capacitance method, oxygen by an electrochemical sensor, and residual hydrogen by catalytic combustion. Each channel has its own specified range, accuracy, and explosion-protection marking; review the technical table for the individual values.
Designed for generator-room service
The electrical section and sensing unit use an integrated explosion-proof design with explosion-proof operation buttons. An oil-filter device is specified to help protect the sensing unit from oil contamination. The explosion-proof unit can be installed independently or with a sampling frame. The product information also describes under-pressure purity and humidity measurement to reduce hydrogen loss associated with evacuation-based measurement.
Plan channel selection and installation together
Before specifying the analyzer, confirm which parameters are required, the generator gas mixtures, operating pressure, sample arrangement, alarm points, output integration, and hazardous-area classification. The purity and humidity channels are stated as Ex d IIB + H₂ T5 Gb; the residual-hydrogen channel is stated as Ex d IIC T6 Gb. Confirm the exact certificate and configuration for the installation site.
For a technical review and quotation, share the generator model, required measurement channels, hydrogen and carbon-dioxide mixtures, sample pressure, alarm and 4–20 mA requirements, mounting arrangement, and commissioning schedule. This supports selection of an H2 quality analyzer for continuous generator cooling-system monitoring.
