The electromagnetic harassment generated by electrical and electronic equipment at work is mainly formed by the action of various electronic circuits, switching power supplies, motors, mechanical switches and protectors inside them. According to its transmission path, the harassment mainly consists of conduction harassment transmitted along the power line and signal line, and radiation harassment emitted to the surrounding space.

In recent years, the qualified rate of national supervision and random inspection of weighing sensor product quality is only 37.5%; The qualified rate of product quality of electronic pricing scales has been hovering around 50%, and most of the unqualified products are because the temperature performance of the weighing sensor is unqualified.

There is a stable and stable connection between the load cell and the ground or floating ground, or through the ground screw on the housing and the ground pile, depending on the specific situation. If there is no interference introduced by the ground conductor propagation path
