The daily maintenance of pressure sensors begins with cleaning. Wipe the surface of the sensor regularly with a mild cleaner and a soft cloth to remove dust and dirt, ensuring that the sensor can accurately sense and measure pressure. In particular, the cleaner should be selected to avoid damage to the sensor seal and electrical connections. For sensors used in humid environments, effective waterproof measures should be taken, such as the use of waterproof shells or waterproof coatings, to prevent moisture from penetrating into the interior of the sensor and affecting its performance. In addition, when wiring, the cable should be passed through the waterproof connector or winding pipe, and tighten the sealing nut to further prevent rainwater, etc., from leaking into the sensor housing through the cable.
