    How to Install CO2 Sensor?

    CO2 sensors are widely used in many fields of work and bring many conveniences to people's lives. The installation position of the CO2 sensor has a great influence on whether it can function perfectly. Next, ATO will introduce you to the installation skills of the CO2 sensor.

    What is a CO2 sensor?

    Carbon dioxide sensors are usually composed of capacitors, which output signals when the voltage and current are stable. Due to the high concentration of the measured gas, only by using enough sensors can the ambient gas reach a certain balance and thus reach a safe value. CO2 sensors are widely used in the industrial field. With the rapid development of technology and other factors, many manufacturers have adopted intelligent control systems.

    Installation Requirements in Coal Mine Areas

    1. The installation location of the sensor should comply with national standards and technical specifications. If it is installed in a coal mining area, it should generally be in the air inlet, air outlet, and ventilation system of the mine area, so as to timely grasp the carbon dioxide concentration in the mine.Carbon dioxide co2 sensor for home
    2. TheĀ CO2 sensor should be installed in an area that is easily polluted to prevent it from being affected by dust, water vapor, etc., which will affect the sensitivity and accuracy of the sensor.
    3. The sensor should be installed in an area that can protect it from accidental damage, mine equipment, or human damage.
    4. The sensor should be inspected and maintained regularly to ensure its normal operation and the damaged or aging equipment should be replaced in time.
    5. The sensor should be linked with other safety monitoring equipment. When the carbon dioxide concentration exceeds the standard, it can timely alarm and take corresponding measures. The correct installation and use of carbon dioxide sensors play a vital role in the safe production of non-coal mines and must be operated in strict accordance with regulations.

    Installation requirements in daily life areas

    Install in a well-ventilated environment out of direct sunlight

    Sunlight can easily change the capacitor in the sensor, thus affecting the normal operation of the sensor. Therefore, when installing the carbon dioxide sensor, pay attention not to being exposed to direct sunlight, and try to avoid exposure to the sun. At the same time, it should be noted that under the condition of no ventilation. It is necessary to avoid using it in an environment exposed to the sun. If it is installed for outdoor use, you need to pay attention to avoid using it when it is raining.

    The installation position is mainly on the wall

    After the carbon dioxide sensor equipment is purchased, the wall is always the first choice to install the carbon dioxide sensor, so that it can provide accurate information for the ventilation system. However, when choosing to install a carbon dioxide sensor on the wall, we should consider keeping the sensor device about 0.3 to 1.8 meters away from the floor, so that theĀ NDIR CO2 gas sensor device can better contact the atmosphere in the air and keep the sensor in a relatively humid environment will not get wet.

    If we have to choose a non-wall installation method when installing equipment, such as pipe installation, then it should be as close as possible to the actual occupied space and facilitate the contact between the sensor equipment and the location to be measured, making maintenance more convenient.

    If you need to install a carbon dioxide sensor on the roof, it is recommended that you try to make the device within the detectable range of every area during installation. If the area is too wide, consider installing a CO2 sensor in each area.NDIR co2 gas sensor 0 to 2000ppm

    Stay away from high-temperature objects to avoid damaging the sensor

    The installation of the sensor needs to prevent high temperatures and prevent the electrodes of the sensor from contact with high-temperature objects, so as to avoid chemical reactions and damage to the sensor. When the electrodes of the sensor are in contact with the air, an oxidation reaction will occur, which will affect the service life of the sensor. When the sensor is transported, it is necessary to prevent sunlight exposure, and the sensor will be damaged if the temperature is too high. The humidity in the installation location should not be too high to prevent the internal components of the sensor from being corroded.

    Forbidden to connect to electricity during installation and use

    In addition, it must be ensured that the horizontal direction of the sensor housing is parallel to the direction of the measured gas. Pay attention to whether there are cracks in the CO2 sensor shell, if there are cracks, the sensor will be electrified. Pay attention to whether there are corrosive substances in the gas to be measured. If there is, it should be replaced immediately to avoid corrosion affecting the accuracy and measurement function of the carbon dioxide sensor.

    Try to use an inert gas with good corrosion resistance for testing

    CO2 in the air is corrosive to metals, so it is recommended to use a gas that is resistant to corrosion and does not corrode metals. The gas source should be turned off immediately after the test. If the air source needs to be turned on during use, the test container should be put into use again.

    Regularly check capacitors and electrodes

    During the use of the sensor, since the concentration of the measured gas is constantly changing, in order to ensure the stability of the sensor's measurement results, it is necessary to replace the capacitor in time. Only in this way can we ensure that the sensor is always in a stable state, thereby ensuring the accuracy of the measurement results.

    The electrode is also a very important part. Once the electrode is damaged, it will affect the signal output by the carbon dioxide sensor. Therefore, it is necessary to regularly check whether the electrodes are damaged and replace them in time. When replacing the electrode, the material should be selected. Generally, materials such as carbon steel should be selected. The electrodes should be kept clean and not in contact with corrosive gases and liquids.
