Accurate monitoring of oxygen content in high-temperature environments is crucial in modern industrial production.As a professional gas composition detection device, the heated zirconia probe has become a key monitoring tool in high-temperature industrial fields such as steel, power, and chemical industry due to its unique working principle and reliable performance.

　　1、 Core function: Accurate measurement of oxygen concentration in high-temperature environments

The core function of the heated zirconia probe is to detect the oxygen content in high-temperature gases in real time. Its working principle is based on the oxygen ion conductivity characteristics formed by zirconia solid electrolytes at high temperatures (usually 700-850 ℃). The probe maintains the working temperature through a built-in heating element, allowing oxygen ions inside the zirconia ceramic tube to move directionally between the electrodes, forming a potential difference related to oxygen concentration. This electrochemical conversion mechanism enables the probe to accurately measure oxygen content within the range of 0.1-20.6%, with a measurement accuracy of ± 1% FS and a response time typically less than 3 seconds.

　　2、 Key application: High temperature process control for multiple industries

In the field of steel smelting, this probe is installed on key equipment such as converters and blast furnaces to monitor the oxygen content during the combustion process in real time, helping to control the air-fuel ratio, ensuring smelting efficiency and reducing fuel consumption. Thermal power plants use this probe to optimize boiler combustion, by accurately adjusting the air coal ratio, the combustion efficiency is improved by 2-5%, and the annual coal cost savings can reach millions of yuan. In the petrochemical industry, probes monitor the gas composition of equipment such as reactors and incinerators to ensure the safety and environmental compliance of the production process. In addition, in high-temperature processes such as glass melting furnaces and waste incineration, this equipment is also a necessary tool for controlling emissions and improving energy efficiency.

　　3、 Technical advantage: Reliable design that adapts to harsh working conditions

The heated zirconia probe adopts a double-layer ceramic tube structure, with an inner tube for sensing gas and an outer tube for protecting components. It can withstand temperatures up to 1000 ℃ or above. Its intelligent heating system has temperature self compensation function and can work stably in ambient temperatures ranging from -20 ℃ to 70 ℃. The heat-resistant design allows the probe to withstand rapid temperature changes, while the corrosion-resistant coating effectively resists the erosion of corrosive gases such as sulfides and chlorides. Modern probes also integrate digital signal processing modules, with automatic calibration, fault diagnosis, and data remote transmission functions, supporting seamless integration with DCS systems.

From energy conservation and emission reduction to safe production, the heated zirconia probe has become a crucial 'golden eye' in high-temperature process control due to its precise measurement capability and reliable industrial performance. With the development of industrial intelligence, such intelligent monitoring devices will continue to play an important role in improving production efficiency, ensuring equipment safety, and achieving environmental goals.
