When the electronic hanging scale is working in the open air, it will cause great damage to the electronic crane scale when it meets thunderstorm and is struck by lightning. Lightning is a common natural phenomenon, and some electronic scales must work in the open-air environment. Facing this situation, how to prevent lightning strikes is particularly important. According to the requirements of modern lightning protection technology, the concept of comprehensive protection, system protection and level by step protection is set up.
The lightning protection that the electronic hanging scale needs to do:

1. special equipotential lightning protection for all parts of the electronic weighing apparatus such as electronic scale sensor and two meter.
2. cut off the electrical channel of the sensor elastomer and scale platform, and provide the discharge channel of the current.
3. power supply system for multilevel lightning protection
4. build a lightning protection grounding network around the electronic scale, including the scale foundation. The whole system is single grounded near the scale.
5. installation of lightning recorder, real-time detection of electronic weighing instrument lightning protection system, the main interference and suppression technology of electronic scale.
1. Power interference
2, alternating current interference
3. Induced interference
4. Radio frequency interference
5, electrostatic interference

The electronic scale generally realizes the above technology. In the thunderstorm day operation, the possibility of being struck by lightning or being disturbed is greatly reduced, which ensures a great majority of safety and does not affect the work process.
