Process oxygen analyzers, also known as oxygen gas analyzers or oxygen concentration analyzers, are instruments specifically designed for measuring and monitoring the oxygen content in industrial processes. These analyzers play a crucial role in various applications, including combustion control, environmental monitoring, chemical processes, and safety systems. Here are some key features and characteristics of process oxygen analyzers:


1. Measurement Principle: Process oxygen analyzers utilize different measurement principles to determine the oxygen concentration in a gas sample. Some common measurement techniques include:


- Paramagnetic: Paramagnetic oxygen analyzers measure the magnetic susceptibility of oxygen, which is proportional to its concentration. This principle is based on the fact that oxygen is weakly attracted to magnetic fields, allowing for accurate and reliable oxygen concentration measurements.
- Zirconia: Zirconia-based oxygen analyzers rely on the electrochemical properties of zirconia to measure the oxygen concentration. Zirconia sensors consist of a solid-state electrolyte that conducts oxygen ions, and the oxygen concentration is determined by measuring the potential difference between the reference and measurement electrodes.
- Galvanic: Galvanic oxygen analyzers operate based on the principle of electrochemical oxidation of oxygen. The oxygen molecules are reduced at the cathode, generating a current that is proportional to the oxygen concentration.
- Optical: Optical oxygen analyzers employ the luminescence quenching phenomenon. The sample gas is passed through a sensor cell containing a luminescent material, and the oxygen molecules quench the luminescence, allowing for oxygen concentration measurement.


2. Measurement Range and Accuracy: Process oxygen analyzers are available in various measurement ranges, typically expressed as a percentage of oxygen concentration. The measurement range can vary depending on the specific application requirements. The accuracy of the analyzer is an important consideration and is typically specified as a percentage of the full-scale range.


3. Sampling System: Process oxygen analyzers incorporate a sampling system to extract gas samples from the process stream. The sampling system may include sample probes, filters, flow control devices, and sometimes sample conditioning components to ensure the gas sample is representative and suitable for analysis.


4. Response Time: The response time of process oxygen analyzers is the time taken to reach a stable measurement after the gas sample is introduced. Faster response times are desirable in applications where rapid changes in oxygen concentration need to be monitored and controlled.


5. Display and Output: Process oxygen analyzers provide real-time measurement data, which can be displayed locally on the analyzer itself. The data may include oxygen concentration readings, trends, alarms, and other relevant information. Additionally, analyzers often offer analog outputs (e.g., 4-20 mA), digital outputs (e.g., Modbus, Profibus), or other communication interfaces for integration with control systems and data acquisition systems.


6. Calibration and Maintenance: Regular calibration and maintenance are necessary to ensure accurate and reliable measurements. Process oxygen analyzers typically require periodic calibration using known gas mixtures or calibration gases. They may also feature self-diagnostic capabilities and automatic calibration routines to simplify the calibration and maintenance process.


7. Hazardous Area Considerations: In certain applications, process oxygen analyzers may need to be designed for installation in hazardous areas where explosive atmospheres may be present. These analyzers are often designed with explosion-proof enclosures and certified according to relevant safety standards.


The selection of a process oxygen analyzer depends on factors such as the specific application, the measurement range required, the environmental conditions, and any applicable industry standards or regulations. It is important to consult with manufacturers or experts to choose the most suitable analyzer for a particular process.

 

Process gas analyzer is an important tool in process safety and quality control. It helps to monitor and optimize the chemical composition of process gases. The gas analyzer market is segmented by type, technology, application, and geography.

 

Our gas analyzers high-stability infrared detector and TDL technology for the simultaneous measurement of CO, CO2, and CH4. These gases are suitable for challenging applications such as syngas and gasification atmospheres. In addition, analyzers may use a compensated thermal conductivity cell for H2. Electrochemical O2 sensors may also measure percent levels of oxygen in the sample gas stream.
