Overview
The Siemens Ultramat 23 (specifically Model 7MB2355-0AG16-3AA1-ZT23) serves as a benchmark in industrial gas analysis for emission monitoring. This robust, TÜV-approved 19" rack-mounted analyzer is engineered to simultaneously measure the concentration of one infrared-sensitive gas (e.g., CO, SO₂, NO) and oxygen (O₂).
It is a critical tool for industries mandated to comply with strict environmental regulations, providing reliable and accurate data for process optimization and regulatory reporting. By integrating infrared (NDIR) and electrochemical technologies into a single, compact unit, it offers a cost-effective and simplified solution for Continuous Emission Monitoring Systems (CEMS).
Key Features & Functional Characteristics
Dual-Technology Design: The model’s core strength lies in combining Non-Dispersive Infrared (NDIR) (for measuring CO, SO₂, or NO) and a separate electrochemical cell (for oxygen concentration), delivering two critical measurement values from one instrument.
TÜV Certification per EN15267: Its official approval under European standard EN15267 is paramount for legally mandated emission monitoring. This certification verifies the analyzer meets stringent quality assurance criteria for performance and reliability.
19" Plug-in Unit for Easy Integration: Designed as a standard 19" rack module (3U height), it simplifies installation into control cabinets or analyzer shelters. This modular approach facilitates maintenance, replacement, and system integration.
Flexible Measuring Ranges: The analyzer supports a wide array of configurable IR measuring ranges—calibratable from minimums (e.g., CO: 0-200 mg/m³) to maximums (e.g., CO: 0-1250 mg/m³)—allowing tailoring to specific application requirements.
External Sample Gas Handling: This variant is supplied without an internal pump, offering flexibility for systems using external sample gas conditioning. Gas connections are 6 mm stubs, compatible with standard tubing.
Technical Performance & Specifications
The performance of the 7MB2355-0AG16-3AA1-ZT1 is defined by high precision and stability—critical for compliance monitoring.
Core Measurement Performance
IR Measurement: The NDIR optical bench is highly stable, resistant to contamination, and delivers excellent long-term accuracy with low drift. This ensures consistent readings even in demanding industrial environments.
Oxygen Measurement: The electrochemical O₂ cell provides a reliable, cost-efficient method for measuring residual oxygen. This is vital for calculating pollutant concentrations normalized to a standard O₂ level (as required by most environmental agencies).
Interface & Control
The unit includes operator software and documentation in English. It typically features:
Standard analog outputs (4-20 mA) for transmitting concentration values;
Digital interfaces (e.g., RS232) for configuration and data logging.

Primary Applications & Use Cases
The analyzer’s primary application is Continuous Emission Monitoring (CEM), making it indispensable for industries with regulated combustion processes:
Waste Incineration Plants: Precisely monitors CO and O₂ concentrations to ensure complete combustion and control the release of harmful pollutants.
Power Generation: Used in coal, oil, or gas-fired power stations to monitor flue gas emissions, ensuring compliance with national and international emission limits.
Cement & Lime Kilns: Monitors emissions from highly abrasive, dusty process gases—requiring robust upstream sample gas conditioning.
Chemical & Petrochemical Industries: Tracks emission levels from various thermal processes and heaters.
Material & Construction
The Ultramat 23 is built for longevity in harsh conditions:
Housing: Durable steel construction provides EMI/RFI protection.
Sample Gas Path: Corrosion-resistant materials (e.g., stainless steel) are used for parts contacting measured gas, enabling resistance to aggressive flue gas components (when paired with proper conditioning).
Product Advantages Summary
Regulatory Compliance: TÜV EN15267 certification makes it a legally recognized tool for emission reporting, ensuring data defensibility.
Integrated Solution: Measures two key parameters (IR gas + O₂) in one device, reducing footprint and cost compared to two separate analyzers.
High Reliability & Low Maintenance: Siemens’ proven NDIR technology ensures stable operation with minimal calibration needs, lowering lifecycle costs.
Configuration Flexibility: Wide IR measuring ranges allow the same analyzer to be used across different applications and concentration levels.
FAQs
1. What is the significance of TÜV EN15267 certification?
This certification is mandatory for legally mandated emission monitoring in many regions. It provides independent verification of the analyzer’s performance, stability, and accuracy—ensuring emission reports are legally defensible and reliable.
2. Why does this model lack an internal sample gas pump?
This design offers flexibility for complex systems: it allows use of external, more powerful pumps (for pulling gas over long distances) and enables aggressive sample gas conditioning (filtering, cooling) before gas reaches the analyzer—protecting the unit and reducing maintenance.
3. Why is simultaneous O₂ measurement important?
O₂ measurement enables normalization of pollutant concentrations (e.g., CO) to a standard reference level (as required by law), correcting for dilution by excess air. It also provides vital data for optimizing combustion efficiency and safety.
4. How do I choose the right IR measuring range?
Select a range where your normal operating value falls between 50-80% of the scale for optimal resolution. Narrow ranges (e.g., 0-200 mg/m³) offer higher precision, while wide ranges (e.g., 0-1250 mg/m³) provide a safety buffer for operational upsets (avoiding data loss from over-ranging).
5. What are the advantages of NDIR technology?
NDIR is highly specific to target gases (minimizing cross-sensitivity) and offers exceptional long-term stability with very low drift. This extends intervals between required calibrations, making it ideal for reliable, continuous emission monitoring in harsh industrial environments.
6. What industries typically use this analyzer?
It is primarily used in industries with combustion processes subject to environmental regulations, including waste incineration plants, power generation facilities, cement/lime kilns, and the chemical industry.
