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.

‌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.

-- Four modes including light, vibration, sound and screen display are used to ensure that on-site workers can operate in a safe environment.In addition to the capacitive sensor, it is also possible to use a quantum infrared sensor to directly detect infrared rays, using an infrared interference filter to select the wavelength and an adjustable laser as the light source, forming a new solid-state infrared gas analyzer.

-- This type of analyzer can complete the gas concentration measurement with only one light source, one measuring chamber and one infrared sensor. In addition, if a filter disc equipped with multiple wavelengths is used, the concentrations of different gases in the multi-component gas can be measured simultaneously. The gas analyzer is used to detect the concentration of flammable or toxic gases in the air, such as too high or too low oxygen. The gas detector usually presets a safe value. If there is an abnormality, an alarm will be issued to remind us to take action. Measures must be taken to avoid unnecessary explosions or poisoning.
