Explosion proof oxygen analyzerWidely used in various industries for combustion monitoring and control processes, and has helped achieve considerable energy-saving effects in various industries. The application areas include energy consuming industries such as steel, electronics and power, petrochemicals, ceramics, paper, food, textiles, as well as various combustion equipment such as incinerators and small and medium-sized boilers.

The zirconia oxygen analyzer adopts solid electrolyte zirconia sensor and microprocessor technology, with functions such as digital display, upper and lower limit alarm, standard 4-20mA current signal output, and relay contact alarm output. Widely used for continuous detection of oxygen concentration in non combustible gases.

Explosion proof oxygen analyzerComposed of a converter and a detector, nanomaterials and advanced production processes are used on the core component of the detector, the zirconia concentration cell. Additives that suppress electrode aging are added to the electrode coating. Greatly improved the accuracy and service life of zirconia measurement probes. The converter adopts intelligent design of single-chip microcontroller and Chinese character LCD display, making data display and function control more user-friendly; Can be connected to various types of DCS data access devices. Make the operation of the instrument simple and easy to master.

Zirconia oxygen analyzer is widely used in power, metallurgy, heating, building materials, electronics and other departments due to its simple structure, easy maintenance, fast reaction speed, and wide measurement range. It analyzes the oxygen content of flue gas in various industrial boilers and kilns, improves combustion efficiency, saves energy, and reduces environmental pollution.

This system consists of a power supply unit, a heating and constant temperature control unit, a zirconium pool electromotive force and internal resistance acquisition unit, and a data communication and processing unit. The technical difficulties in designing zirconia probes include precise temperature control technology and weak signal extraction technology for zirconium pool electromotive force. The stability of the constant temperature directly determines the stability of the measurement, while the purity and flow rate stability of the standard gas also affect the test results. The inconsistency of actual industrial field conditions and the production process of sensor probes also affect the final measurement error. The main control adopts STM32F103VET6 microcontroller from STMicroelectronics, and the control and communication use magnetic isolation digital signals. The acquisition unit adopts differential high impedance operational amplifier output and attenuation to adapt to wide range dynamic testing; The heating system adopts high-speed optocoupler isolation and high-power thyristor driven heater to meet the requirements of fast control and constant temperature.

Zirconia oxygen analyzer (hereinafter referred to as the analyzer) is a high-tech product that uses solid electrolyte oxygen sensors and has been widely used in industries such as power plants, pharmaceutical factories, and oil fields. Due to its role in "energy conservation" and "environmental protection", it is highly favored by people.

Zirconia analyzers come in both integrated and split types, with measurement characteristics such as high sensitivity, good reproducibility and stability, wide range, automatic switching, fast response, and continuous online measurement. At the same time, zirconia analyzers can be used in conjunction with various electric unit instruments, conventional display recorders, and DCS distributed control systems. How to avoid errors caused by the use of zirconia analyzer during the measurement process, if the zirconia analyzer outputs 4-20mA or has remote transmission functions such as communication?
1. The measurement requirements of zirconia analyzer must effectively eliminate various interface valves and fittings in the gas path, and the pollution caused by dead corners in the measurement process of zirconia probe to the sample gas. So, we should simplify the gas path system as much as possible and choose measurement points with small blind spots. At the same time, it is advisable to avoid using equipment such as water seals, oil seals, and wax seals as much as possible to prevent smoke from escaping and causing pollution. It is also necessary to avoid adding purification equipment that can easily cause pollution to the pipeline leading from the sample gas to the inlet of the zirconia analyzer. Only in this way can we ensure the cleanliness of the system and the accuracy of the data obtained.
2. When using a zirconia analyzer for measurement, we must pay attention to whether there is air leakage when connecting the measuring pipeline of the zirconia analyzer, ensure sealing, and blow off the air from the probe as much as possible to prevent a large amount of oxygen from passing through the sensor of the zirconia analyzer, in order to extend the sensor life and measurement accuracy.
3. The material and surface roughness of the zirconia analyzer pipeline will also affect the changes in oxygen content in the sample gas. Under normal circumstances, it is not advisable to use plastic pipes, rubber pipes, etc. as connecting pipelines, and attention should be paid to gas sealing. Zirconia analyzer (trace oxygen analyzer) usually uses copper or stainless steel tubes, and for ultra trace analysis (referring to<0.1ppm), polished stainless steel tubes must be used.
4. The direct insertion zirconia analyzer must undergo strict leak detection before use to prevent air leakage and measurement values from being biased. The zirconia micro oxygen analyzer can only obtain accurate data results under the premise of being tight and leak proof. Any loose connection points, welding points, valves, etc. in the gas path will also cause oxygen in the air to seep back into the pipeline and inside the zirconia analyzer, resulting in high oxygen content. In the purification process of pipeline systems, in order to shorten the purification time, certain methods are needed. Generally, high-pressure venting and low flow blowing are alternately used to quickly purify the analyzer pipeline.
