Analytical 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.

Analytical 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.

How to calibrate zirconia probes regularly?

This probe can be calibrated after three days of normal operation. If any abnormal phenomena are found during use, the zirconia sensor can be calibrated using standard gas on the premise that the transmitter self-test is normal and the temperature control system is normal. For instruments that are working normally, calibration is generally conducted once a month. Special attention should be paid to two points: first, to prevent the zirconia sensor from being damaged by the impact of the standard gas; second, after adjusting the flow rate, connect the gas guide pipe to the standard gas inlet to prevent waste caused by gas leakage. When opening the top gas valve of the gas cylinder, it should be slowly rotated. If there is a gas leakage phenomenon (hissing sound), the gas valve should be closed, the connecting device should be reinstalled, and then after calibration is completed, the top gas valve of the gas cylinder should be closed (clockwise) to prevent loss caused by long-term gas leakage.
