Product Introduction

1. Siemens infrared gas analyzers (such as Ultramat 23 series) use ‌non-dispersive infrared technology (NDIR)‌, which is specially designed for industrial gas concentration measurement and suitable for continuous monitoring of multiple gases (such as CO, CO₂, CH₄, SO₂, etc.), with high precision, strong anti-interference and good long-term stability.

‌2. Typical application scenarios‌
‌-- Industrial process control‌: gas concentration monitoring in chemical, petrochemical and power industries.
‌-- Environmental emission monitoring‌: flue gas emissions (such as NOx, SO₂), greenhouse gas detection.
-‌- Safety protection‌: flammable or toxic gas leakage alarm.
‌-- Laboratory analysis‌: gas purity or mixing ratio detection.

‌3. Technical Parameters

‌Measuring principle‌: Non-dispersive infrared (NDIR)
‌Measuring range‌: Customized according to gas type (e.g. CO: 0-1000 ppm, CO₂: 0-20% vol)
‌Accuracy‌: ±1% full scale (FS)
‌Response time‌: ≤10 seconds (T90)
‌Output signal‌: 4-20 mA, RS-232/RS-485, Ethernet (optional)
‌Ambient temperature‌: -5°C to +45°C (operating temperature)
‌Protection level‌: IP65 (dustproof and waterproof)
‌Power supply‌: 100-240 V AC, 50/60 Hz

‌4. Product Features‌
‌4.1 High reliability‌
- Anti-vibration and corrosion-resistant design, suitable for harsh industrial environments.
‌4.2 Modular structure‌
- Supports expansion of multi-gas measurement modules.
‌4.3 Intelligent diagnosis‌
-- Self-check function, fault alarm and historical data storage.
‌4.4 Low maintenance cost‌
-- Long-life infrared light source and gold-plated gas chamber to reduce calibration frequency.

-- High monitoring sensitivity: High monitoring sensitivity, can distinguish small changes in gas concentration.

-- High measurement accuracy: Generally in FS (full scale), compared with other analysis methods, it has higher accuracy and good stability.

-- Fast response speed: The response time is generally within 10S (time reaches T90).

-- Low maintenance cost: With air self-calibration function, high efficiency does not require calibration gas and accessories, and is almost maintenance-free. Multi-layer detection -- ensures high accuracy and small lateral sensitivity. The sampling unit is easy to clean, reducing maintenance costs.

-- Easy operation: With menu-assisted operation in simple text format, it can be operated and controlled without manual, which is very safe.

-- Good data integration: open interface structure (RS485, RS232, PROFIBUS, SIPROMGA), simplified process integration, remote control, data can be imported into other systems.

‌5. Precautions for use‌
‌-- Installation environment‌: Avoid strong electromagnetic interference or drastic temperature fluctuations.
‌-- Calibration cycle‌: It is recommended to calibrate the standard gas every 6-12 months.
‌-- Gas path treatment‌: Filters and dehumidification devices are required to prevent probe contamination.
