Overview
The Siemens Ultramat 23 (Model 7MB2337-4AU86-6PT1-ZC11+D15) is a premium-configured analyzer engineered for applications demanding maximum accuracy in multi-gas analysis. This sophisticated 19" plug-in unit simultaneously measures three key parameters: two infrared-sensitive gases (CO and NO) and oxygen (O₂)—with O₂ detected via a high-precision paramagnetic method.
Unlike models with combined gas paths, it features separate gas paths to enhance analytical integrity. This design makes it ideal for rigorous environmental compliance reporting and precise process control in complex industrial settings where data reliability is non-negotiable.
1. Technological Highlight: Paramagnetic Oxygen Sensing Explained
A defining feature of this model is its paramagnetic O₂ sensor—a significant upgrade from basic electrochemical cells. Its working principle leverages oxygen’s unique paramagnetic property (attraction to magnetic fields) and operates as follows:
The sensor uses a delicate "dumbbell" assembly (filled with nitrogen) suspended in a magnetic field.
When sample gas containing O₂ enters the sensor, O₂ molecules are drawn to the strongest part of the magnetic field, creating a measurable force that deflects the dumbbell.
This deflection is directly proportional to O₂ concentration.
This method delivers exceptional accuracy, long-term stability, and minimal drift—because it measures a fundamental physical property, not a chemical reaction that degrades over time.
2. Key Differentiator: Separate Gas Paths for Uncompromised Measurement
Unlike previous models with combined gas paths, this analyzer uses separate gas paths (2 Channels). The sample gas is split into two independent streams, each dedicated to one IR component (CO or NO).
This advanced design is critical for applications where:
The two IR gases might interact chemically;
One gas could optically interfere with the other’s measurement in a shared chamber.
Separate paths ensure each component’s measurement remains fully isolated and pure, delivering the highest data integrity for critical decision-making.
3. Product Specifications and Advanced Features
This model is optimized for high-precision emission monitoring, with ranges specified in mg/m³ (the standard unit for regulatory reporting) and built-in flexible unit conversion.

4. Critical Application: The Role of O₂ Normalization in Emission Reporting
The combination of high-accuracy IR gas measurement (in mg/m³) and a paramagnetic O₂ sensor makes this analyzer a cornerstone of legally mandated emission monitoring.
Environmental regulations often require pollutant concentrations (e.g., CO, NOₓ) to be normalized to a standard O₂ level (e.g., 3% or 11%)—this corrects for dilution by excess air. The paramagnetic O₂ sensor’s superior accuracy ensures this normalization calculation uses reliable data, which is critical for generating legally defensible compliance reports and avoiding penalties.
5. Advantages Summary
Superior O₂ Accuracy: Paramagnetic technology delivers unmatched precision and stability for O₂ measurement—essential for compliance.

Frequently Asked Questions (FAQs)
What is the advantage of a paramagnetic O₂ sensor over an electrochemical one?
Paramagnetic sensors measure O₂’s physical magnetic property—offering better long-term accuracy and stability with no degradation. Electrochemical cells have limited lifespans, drift over time, and require frequent replacement/calibration.
2. Why would an analyzer need separate gas paths for different components?
Separate paths prevent chemical interaction or optical interference between gases in a shared chamber. This ensures fully independent measurements, critical for high-integrity data in compliance or precision process control.
3. What does "SO₂ 100 mg not certified" mean?
The analyzer can be configured to measure SO₂ at 100 mg/m³, but this measurement lacks formal certification (e.g., TÜV). It is suitable for process monitoring but not legally mandated SO₂ reporting.
4. Why is the 60 Hz power supply significant?
60 Hz is the standard electrical frequency in North America and other regions. This specification ensures compatibility with local grids, eliminating the need for external frequency converters.
5. What is the purpose of selectable temperature (293K/273K) for unit conversion?
273K (0°C) and 293K (20°C) are common reference temperatures for unit conversion. Selecting the correct one ensures accuracy when converting mg/m³ to ppm, aligning with regional/industry reporting requirements.
6. How does the "Dumbbell" paramagnetic sensor work?
A nitrogen-filled "dumbbell" is suspended in a magnetic field. When sample gas enters, paramagnetic O₂ molecules are drawn to the magnetic field’s strongest area, deflecting the dumbbell. This deflection is measured optically and correlates directly to O₂ concentration.
