Why TSRAI NANOZ sensors outperform conventional gas analysis in steel plant applications
| Parameter | Traditional Methods (NDIR, Electrochemical, GC) | NANOZ MEMS MOX with AI |
|---|---|---|
| Response Time | 30-120 seconds (sample extraction + analysis) | <3 seconds (T90) — direct measurement |
| Multi-Gas Capability | Separate analyzers per gas (CO, CO₂, H₂, CH₄) | 12+ gases with single sensor array |
| Accuracy | ±3-5% (affected by cross-sensitivity, drift) | ±2% with AI drift compensation |
| Calibration Interval | Monthly/quarterly (manual, production stoppage) | 6-12 months with self-diagnostics |
| Maintenance Cost | High (sample conditioning, filters, electrodes) | 80% lower — no sample conditioning |
| Installation | Complex sample lines, heated, climate-controlled | Direct mount, IP67, no conditioning |
| Capital Cost (per point) | ₹15-30 Lakhs per analyzer | ₹3-8 Lakhs per sensor node |
| Operating Temperature | Typically max 60°C (requires cooling) | -40°C to +85°C continuous |
| Cross-Sensitivity | Significant (NDIR: H₂O, EC: H₂S interference) | AI-corrected — near-zero interference |
| Sensor Lifespan | 1-2 years (electrochemical cells degrade) | 3-5+ years (MEMS MOX stability) |
| ATEX/Hazardous Area | Requires expensive Ex enclosures | II 2G Ex ia IIC T6 Gb certified |
| Data Output | 4-20mA analog typical | 4-20mA, Modbus RTU/TCP, OPC-UA, MQTT |
Meeting domestic Green Steel standards and CCTS compliance demands real-time process monitoring
India's steel industry accounts for ~12% of national CO₂ emissions. The National Steel Policy targets significant emission intensity reduction by 2030.
India's PLI scheme (Dec 2024) introduced Green Steel ratings. Qualifying opens access to government projects and premium pricing.
The Carbon Credit Trading Scheme mandates emission intensity targets for 253 steel entities from FY2026. NANOZ provides verified MRV data.
