A Zirconia Oxygen/Humidity Analyzer is a specialized instrument used to measure the concentration of oxygen and humidity in various gas streams. It utilizes zirconia-based sensors to make accurate measurements.
Zirconia oxygen sensors are based on the principle of the oxygen concentration cell. They consist of a solid-state electrolyte made from stabilized zirconia material. The sensor operates by creating a voltage potential across the electrolyte, which is dependent on the oxygen concentration difference between the sample gas and a reference gas. The zirconia material acts as an oxygen ion conductor, allowing oxygen ions to pass through the electrolyte.
In the case of a Zirconia Oxygen/Humidity Analyzer, the zirconia sensor is combined with a humidity measurement component to simultaneously measure both oxygen concentration and humidity in the gas sample.
The analyzer typically consists of the following components:
- Zirconia oxygen sensor: This sensor measures the oxygen concentration in the gas sample. It consists of a zirconia-based electrolyte and electrodes.
- Humidity sensor: This sensor measures the humidity or moisture content in the gas sample. Various types of humidity sensors can be used, such as capacitive or resistive sensors.
- Signal processing and display: The analyzer includes electronics for signal processing and conversion of the sensor outputs into meaningful measurements. It may have a display unit to provide real-time readings of oxygen concentration and humidity.
- Gas sampling system: A gas sampling system is used to extract a representative sample of the gas for analysis. It may include filters, pumps, and flow control devices to ensure a proper and consistent gas sample is delivered to the analyzer.
- Calibration system: Periodic calibration is necessary to maintain the accuracy of the analyzer. A calibration system is used to verify and adjust the readings of the oxygen and humidity sensors.
Zirconia Oxygen/Humidity Analyzers find applications in various industries such as power plants, combustion processes, environmental monitoring, and industrial gas production. They are used to monitor and control oxygen levels and humidity in processes, optimize combustion efficiency, and ensure compliance with environmental regulations.
