As an accurate detection device, if the sensor is damp, it will be troublesome, the sensor will affect its accuracy and stability when it is damp, and it will form a problem if the sensor is used in a more important place, then the loss of the formation is very heavy. In 08 there was a plane crash caused by the sensor damp, the sensor moisture to obtain the information also deviated from the trajectory, the aircraft was affected by the sensor fault information, the flight speed, elevation angle are wrong, resulting in the loss of control of the aircraft. It can be seen that the importance of moisture-proof sensors is important, so how to prevent moisture?
1. Encapsulating the resistance strain gage, that is, covering the strain gauge with waterproof material;
2. To manipulate the environment or create a low humidity environment, it is necessary to prevent moisture from entering the sealed load sensor;
Third, it is necessary to ensure a high-quality composite waterproof seal that keeps the sensor's components unaffected and has minimal permeability throughout the operating temperature. The high-quality sensor cable tightly binds the conductor to the housing and prevents moisture from entering the interior through the cable core.
Fourth, if it is a welding seal, glass and metal cable joints are sometimes very useful. After these treatments, the moisture resistance of the sensor is maximized.
