Product Introduction

‌1. Product Overview‌
‌-- Model and Series‌: Siemens ULTRAMAT 23 series online gas analyzer, model ‌7MB2335-0PG00-3AA1, designed for continuous monitoring of multi-component gases in flue gas‌.
‌‌-- Measurement Principle‌: Based on ‌non-dispersive infrared (NDIR) technology‌ and ‌electrochemical sensors‌, it supports simultaneous detection of infrared sensitive gases such as CO, CO₂, NO, SO₂ and O₂‌.
‌‌-- Core Function‌: Suitable for industrial emission monitoring and combustion optimization, and can meet the real-time data requirements of environmental protection standards (such as flue gas pollutant concentration limits).
2. Technical Parameters‌

‌Measurement Range‌: Customizable (such as CO: 0-1000 ppm, CO₂: 0-5% vol, O₂: 0-25% vol).
‌Accuracy‌: Resolution ≤0.01 vpm (H₂S), linear error ≤1% FS, stability drift ≤1% FS/week‌.
‌Output interface‌: RS-232/RS-485, Profibus, supports 4-20 mA analog signal transmission‌.
‌Power supply and protection‌: AC220V±10%, 50 Hz; IP65 protection level, suitable for high temperature and dusty environment‌.
‌Transmission distance‌: Maximum 500 meters (can be extended by repeater).
3. Core functions and advantages‌
‌3.1 Multi-component high-precision detection‌
--Synchronous analysis of 3 infrared gases + O₂, multi-layer detector design reduces cross-interference‌.
‌3.2 Intelligent maintenance‌
--Supports automatic calibration of ambient air (zero point calibration), infrared channel and O₂ sensor can be self-calibrated regularly to reduce manual intervention‌.
‌3.3 Industrial-grade reliability‌
-- Corrosion-resistant air chamber materials and anti-vibration structures are suitable for high-pollution scenarios such as coal-fired boilers and incinerators.
‌3.1 User-friendliness‌
-- Plain text menu operation interface, equipped with fault self-diagnosis and log recording functions, simplifying the operation and maintenance process.
4. Typical application scenarios‌
‌4.1 Industrial emission monitoring‌: Real-time monitoring of CO, NOx, and SO₂ in coal-fired/gas-fired boilers and waste incineration plants.
‌4.2 Combustion optimization‌: Optimize combustion efficiency and reduce pollutant emissions through flue gas composition analysis.
‌4.3 Safety warning‌: Monitoring of combustible/toxic gas leaks in the chemical and power industries.
5. Precautions for use‌
‌5.1 Installation requirements‌
A pre-filter and dehumidification device are required to prevent particulate matter or moisture from contaminating the air chamber.
‌5.2 Calibration Specifications‌
O₂ calibration relies on ambient air, and infrared components need to be verified regularly with calibration gas (e.g. CO₂ calibration requires pretreatment with a soda lime absorber).
‌5.3 Compatibility Limitations‌
The hardware must meet minimum configuration (e.g. 486DX-66 processor with 8 MB RAM, Windows 95/98/NT system).
