company news about Nitrogen Oxygen Sensor User Guide

I. Installation Location and Requirements
        Nitrogen oxide sensors are usually installed at key locations in the engine emission system to detect the nitrogen oxide content in the exhaust gas in real time. During installation, ensure that the sensor is tightly connected to the exhaust pipe and there is no leakage. At the same time, avoid installing the sensor in an environment with high temperature, high humidity or strong vibration to avoid affecting its measurement accuracy and service life.

II. Working Principle and Function
        Nitrogen oxide sensors detect the nitrogen oxide content in the exhaust gas by chemical or electrochemical methods and convert it into electrical signals for output. The main function of the sensor is to monitor the nitrogen oxide concentration in the exhaust in real time and provide data support for the vehicle's emission control system to achieve precise adjustment of the engine's operating status, thereby reducing exhaust emissions.

III. Power Supply and Voltage Requirements
       Nitrogen oxide sensors usually require a stable DC power supply. The specific power supply voltage and current requirements should refer to the sensor manual or the vehicle manufacturer's regulations. During installation and use, ensure that the power supply line is connected correctly and there is no short circuit or open circuit to avoid affecting the normal operation of the sensor.

IV. Fault Diagnosis and Treatment
       If the nitrogen oxide sensor fails, it may cause the vehicle to exceed the emission standard or the engine to operate abnormally. Common fault phenomena include abnormal sensor signals, no signal output, etc. When diagnosing a fault, you should first check whether the power supply line is normal, and then check whether the sensor itself is damaged. If the sensor fails, a new nitrogen oxide sensor should be replaced in time.

V. Cleaning and maintenance
      During use, the nitrogen oxide sensor may be affected by pollutants such as oil and dust in the exhaust gas, resulting in reduced measurement accuracy. Therefore, it is necessary to clean and maintain the sensor regularly. When cleaning, use a special detergent or alcohol, and avoid using water or other corrosive liquids. At the same time, check whether the installation connection of the sensor is tight to ensure its normal operation.

VI. Storage and transportation conditions
     When storing and transporting nitrogen oxide sensors, they should be placed in a dry, ventilated, non-corrosive gas environment. Avoid long-term exposure to high temperature, high humidity or direct sunlight. During transportation, anti-vibration and anti-impact measures should be taken to avoid damage to the sensor.

VII. Precautions and taboos
     1. When installing and using nitrogen oxide sensors, relevant safety regulations and operating procedures should be followed to avoid accidents such as electric shock and burns.
     2. It is forbidden to disassemble or modify the internal structure of the sensor at will to avoid affecting its measurement accuracy and safety.
     3. It is forbidden to expose the sensor to strong magnetic fields, strong electric fields or radio frequency interference environments to avoid interfering with the normal operation of the sensor.

VIII. Regular inspection and calibration
     In order to ensure the measurement accuracy and stability of the nitrogen oxide sensor, regular inspection and calibration should be carried out. The specific inspection cycle and calibration method should refer to the sensor manual or the vehicle manufacturer's regulations. During the inspection and calibration process, special calibration equipment and standard gases should be used to ensure the accuracy and reliability of the calibration results.
     In summary, the correct use and maintenance of nitrogen oxide sensors are of great significance to ensure the normal operation of vehicle emission control systems and reduce exhaust emissions.
