The Zirconia Oxygen/Humidity Analyzer Is Designed With A High-Temperature Resistant Structure,Humidity And Oxygen Output
Here are some key details about zirconia oxygen analyzers:
- Measure the concentration of oxygen (O2) in a gas sample.
- Use a zirconium dioxide (ZrO2) sensor that conducts ions of oxygen at high temperatures.
- The sensor tip is exposed to the sample gas on one side and a reference gas (usually air) on the other.
- Oxygen ionizes on the sample side and migrates through the zirconia sensor, causing a voltage difference proportional to the O2 concentration.
- Operate at high temperatures 600-800°C to allow oxygen ion conduction.
- Wide measuring range - can detect from ppm levels to 100% oxygen.
- Fast response times in the 10-20 seconds range.
- Not consumed or altered by the measurement, so a very long lifetime.
- Require a conditioning period on startup to stabilize the sensor.
- Minimal drift so infrequent calibration required. Periodic air calibration is adequate.
- Used widely for combustion control, inert gas blanketing, food packaging, and other processes requiring oxygen measurement.
- Benefits are high accuracy, excellent repeatability, long term stability.
- Limitations are high operating temperatures and susceptibility to sensor cracking from thermal shock.
- Major manufacturers include ABB, Teledyne Analytical Instruments, Fuji Electric, and Servomex.
In summary, zirconia oxygen analyzers offer excellent performance for a wide span of O2 measurements in many industrial processes.
