Double-beam NDIR gas analyzer (ZSU, ZKJ) The amount of infrared rays absorbed by a sample cell is detected by the mass flow sensor. The flow rate change is proportional to the oxygen concentration of the sample gas. Oxygen analyzers contain electrical furnaces, so they cannot be used in explosion-proof zones. Most applications are measured in-situ, reducing installation and maintenance costs. It is attracted in an uneven magnetic field and flows to a stronger magnetic field. Oxygen Analyser working principle. The gas sample of the “Gold Net-Pb” primary battery directly enters the solution, resulting in a large amount of instrument maintenance and fuel The battery method sample gas does not directly enter the solution, and the sensor can work very stably and reliably for a long time. ... (Electro Motive Force) which is measured to calculate the oxygen concentration. In industrial water treatment, dissolved oxygen levels can be an indicator of water quality issues that lead to corrosion of equipment. Relatively inexpensive in comparison with oxygen analyzers of other measurement systems. Also inert gas systems use exhaust gases which must be monitored to ensure that their oxygen content is below 5%. How does an oxygen analyzer work and what are the types of oxygen analyzer. The sample gas does not directly enter the sensor, so the solution and lead electrodes do not need to be cleaned or replaced regularly. As it is a kind of oxygen cell, the galvanic cell deteriorates even if not used. Oxygen analyzers provide valuable measurements in combustion control, process quality, safety and environmental applications. This is scaled to give percentage oxygen directly.
