Rosemounte CX2100 in Situ Oxygen Analyzer Flue Gas Oxygen Measurement

The Rosemount CX2100 In Situ Oxygen Analyzer is a high-performance oxygen measurement solution designed to deliver continuous, real-time monitoring of oxygen concentration directly within combustion processes. As part of Emerson’s trusted Rosemount Analytical product line, the CX2100 combines accuracy, robustness, and minimal maintenance requirements, making it ideal for power plants, petrochemical refineries, and industrial boilers.

By providing in situ measurement—without the need for extractive sampling—the CX2100 helps operators maintain ideal air-to-fuel ratios, optimize combustion efficiency, and reduce excess oxygen levels that contribute to higher fuel costs and emissions.

Q1: What is the measurement principle of the CX2100 analyzer?A: The CX2100 uses a zirconia oxide sensing cell to measure oxygen concentration directly in the process gas.

Q2: How is in situ measurement different from extractive sampling?A: In situ systems measure oxygen directly within the process stream, offering faster response and fewer maintenance requirements compared to extractive analyzers.

Q3: Can the CX2100 be used in high-temperature flue gas applications?A: Yes, with appropriate probe selection, it can operate reliably in temperatures up to 700°C.

Q4: What communication protocols are supported?A: The CX2100 supports analog 4–20 mA output with HART communication.

Q5: How often does it require calibration?A: The CX2100 is designed for extended calibration intervals, typically only requiring verification once or twice per year depending on process conditions.
