The maintenance of pressure sensors is the key to ensure their long-term stable operation and extended service life. First, it is essential to clean the sensor surface regularly to remove dust and dirt and prevent it from affecting the sensor's perceptual accuracy. During the cleaning process, use mild cleaners and soft cloths and avoid strong corrosive cleaners that may damage the sensor seal and electrical connections. In addition, waterproof protection cannot be ignored, especially for sensors used in humid environments, waterproof measures need to be taken, such as the use of waterproof shells or coatings to prevent moisture from penetrating into the interior and causing damage. At the same time, periodically check the fastness of cable connections and connectors to ensure that electrical connections are stable and reliable to avoid signal transmission problems caused by loosening or damage.
