How to use the oxygen probe correctly? Tangshan oxygen probe manufacturer to take you to understand

Metallurgical sensors may encounter a variety of problems in the work, these problems may stem from environmental factors, mechanical factors, electrical factors and the characteristics of the sensor itself and other aspects. The following is a detailed summary of these problems by Tangshan fixed oxygen probe manufacturers:

First, environmental factors

High temperature: The metallurgical environment temperature is usually high and fluctuates greatly, which will change the elastomer material characteristics of the sensor, resulting in thermal expansion and cold contraction, resulting in uneven strain gauge stress, which affects measurement accuracy and stability. The high temperature heat conduction temperature of the weighing sensor used in the metallurgical field can reach 170~200℃, especially after a period of use, the thermal conductivity temperature of the weighing sensor is not easily distributed, and the high temperature resistance of the weighing sensor is higher.

Dust: There is a large amount of dust in the metallurgical site, which may block the gaps and vents of the sensor, affecting the normal operation of the sensor.

Water vapor and corrosive gases: Water vapor may erode the circuit of the sensor, and corrosive gases may damage the sensor's sensitive components and housing, reducing the reliability and life of the sensor.

Second, mechanical factors

Material shock and vibration: In metallurgical production, the sensor frequently withstands the impact and vibration of the material, and the long-term effect will loosen, displace or damage the internal components, resulting in zero drift and increased measurement error.

Improper installation: Installation problems such as tilt, eccentricity or improper fixing will make the sensor unevenly stressed, unable to accurately measure weight, and even damage the sensor in serious cases.

3. Electrical factors

Strong electromagnetic field interference: there is a strong electromagnetic field in the metallurgical environment, which will affect the signal transmission and processing of the sensor, causing distortion and fluctuation of the output signal, resulting in inaccurate measurement data.

Power supply stability: the power supply stability of the sensor itself is also crucial, if the power supply voltage is unstable, it will cause the sensor to work abnormally, affecting the measurement accuracy and reliability.

Fourth, the sensor itself characteristics

Measurement range and accuracy limitations: The measurement range and accuracy of the sensor may not meet the actual needs of metallurgical production, resulting in inaccurate measurement data or unable to provide effective measurement information.

Long-term stability: During the long-term use of the sensor, due to factors such as material aging and environmental changes, its performance may gradually decline, affecting the accuracy and stability of the measurement results.

In summary, the problems that may be encountered in the work of metallurgical sensors involve many aspects, which need to be comprehensively considered and effective measures taken to prevent and solve. For example, high temperature and corrosion resistant sensor materials can be selected, the structural design of the sensor can be optimized to improve its impact and vibration resistance, and the installation and maintenance of the sensor can be strengthened to ensure its normal operation. At the same time, the sensor needs to be calibrated and tested regularly to ensure the accuracy and reliability of its measurement results.
