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.

4.5 Automatic calibration

-- With automatic calibration function, drift can be ignored.

4.6 Output signal

-- Support 0/2/4-20mA output signal.

4.7 Load resistance

-- Load resistance does not exceed 750Ω.

4.8 Display mode

-- Equipped with LCD backlight display.

4.9 Repeatability

-- Repeatability is less than or equal to 1% of the small range.

‌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.
