In addition to daily cleaning and calibration, regular inspection is also an important measure to maintain the pressure sensor. This includes checking the sensor surface for physical damage such as scratches, cracks or corrosion, as well as checking that cable connections and connectors are strong. If any abnormality is found, measures should be taken in time to repair or replace the sensor. In addition, rational use is also the key to extend the life of the sensor. The use of sensors in inappropriate environments, such as corrosive or overheated media, should be avoided, as well as to prevent sediment deposition in the conduit. When measuring liquid pressure, attention should also be paid to preventing the impact of the liquid (water hammer phenomenon) to avoid overpressure damage to the sensor. Through reasonable use and regular inspection and maintenance, the service life and performance of the pressure sensor can be extended to a large extent.
