Large-scale electronic weighing instruments such as floor scales are generally located in outdoor open spaces. Large metal components such as weighing platforms and rails are easily attacked by lightning, and are especially prone to surge voltages caused by electromagnetic induction. Therefore, sensors installed under the weighing platform And its connected secondary instruments and corresponding computer systems are easily damaged by lightning strikes. In most cases, since the sensor elastomer is in electrical communication with the weighing platform, this is the main reason why large electronic weighing instruments are often damaged by lightning strikes.

Rainwater contains a small amount of sulfur dioxide and nitrogen dioxide. Rainwater will cause a short circuit in the Guangxi weighbridge circuit, and the humidity of the air will also cause some electronic components to rust, thereby increasing the probability of being struck by lightning, so waterproofing is also necessary; rainwater and lightning are both It may cause certain damage to the weighbridge, rain and lightning strikes need to be protected, and potential small problems should be prevented and dealt with to avoid causing greater damage.
