The nitrogen generator equipped with a built-in high-precision online purity testing device is an intelligent gas-making equipment developed for industries with strict nitrogen purity threshold standards, integrating nitrogen production, real-time component detection, data recording and linkage adjustment into one integrated system. The core online testing module adopts imported electrochemical oxygen concentration sensors and infrared gas analysis probes, which conduct full-component real-time sampling detection on finished nitrogen at the gas outlet pipeline without manual sampling or offline laboratory testing. Different from traditional periodic manual detection, the online purity testing system performs 10 times per second high-frequency sampling analysis, accurately detecting oxygen residual content, water vapor content and impurity gas content in finished nitrogen, and converting data into real-time nitrogen purity value displayed on the industrial touch screen. The detection accuracy reaches 0.01% purity grade, covering full purity detection range from low-purity 90% nitrogen to ultra-high-purity 99.9995% semiconductor-grade nitrogen.
This model features automatic linkage adjustment between the online testing system and the nitrogen generation control program, which is its core differentiated advantage over ordinary nitrogen generators. Once the online detector identifies that nitrogen purity drops below the preset industry threshold due to molecular sieve aging, air source humidity fluctuation or pipeline pressure fluctuation, the PLC central control system will automatically adjust adsorption pressure, purge time and air intake flow within 0.3 seconds to restore qualified nitrogen purity. Meanwhile, the system will automatically cut off unqualified nitrogen discharge and guide substandard gas back to the air pretreatment circulation pipeline for secondary separation, preventing unqualified nitrogen from flowing into production pipelines and causing product scrappage or production safety risks. All purity detection data, operation adjustment records and abnormal alarm records are automatically stored in the built-in industrial memory for 3 years, supporting traceability audit for pharmaceutical, food and electronic manufacturing quality inspection.
The online purity testing device supports multi-mode alarm and remote notification functions, including on-site acousto-optic alarm, factory intranet data push and mobile terminal fault reminder. Users can set multi-level purity early warning values according to production process standards to realize graded risk control. The testing probe adopts dust-proof and anti-corrosion encapsulated structure, adapting to oily, dusty and slightly corrosive on-site gas environments, and only needs annual calibration to maintain long-term detection precision. This intelligent nitrogen generator is prioritized for pharmaceutical packaging inert protection, lithium battery production anti-oxidation, food modified atmosphere packaging, electronic chip welding and laboratory gas supply fields, where nitrogen purity stability must be 100% guaranteed throughout the whole production process.
