Zirconia oxygen sensor

Product Description

1. Zirconia Sensor Element: The core component is a zirconium dioxide (zirconia) ceramic, typically doped with yttria, that functions as a solid electrolyte. When exposed to high temperatures, zirconia allows oxygen ions to move through its lattice structure, generating a voltage that corresponds to the oxygen concentration.

2. High Temperature Tolerance: These analyzers work effectively at high temperatures, often above 600C (1112F), making them suitable for environments like flue gas, combustion chambers, and kilns.

3. In-Situ Installation: As an in-situ device, it measures directly within the gas flow. This design eliminates the need for sample extraction and conditioning, making it quicker to respond to changes in oxygen levels.

4. Electrochemical Principle: Zirconia-based analyzers leverage the Nernst equation, which relates the EMF (voltage) generated across the zirconia electrolyte to the partial pressure of oxygen in the measured gas.

5. Fast Response Time: Due to the direct measurement approach and high-temperature functionality, these analyzers offer a fast response time, critical for controlling combustion processes efficiently.

Applications

• Combustion Control: Used in power plants, cement kilns, steel manufacturing, and petrochemical industries to optimize combustion, reduce emissions, and improve fuel efficiency.
• Process Safety: Monitoring oxygen levels to prevent explosive mixtures or ensure safe operating conditions.
• Environmental Compliance: Helps in maintaining low oxygen levels to control NOx and CO emissions.

Benefits

• Real-Time Measurement: Instantaneous data helps optimize processes.
• Low Maintenance: Limited or no need for gas sampling lines, reducing downtime.
• Durability: Designed for continuous operation in challenging industrial environments.

In-situ zirconia-based oxygen analyzers provide essential control and monitoring capabilities in various high-temperature industrial processes, ensuring both efficiency and safety.
