With the development of society, electronic technology is widely used in different fields, and electronic scale is also very common in daily life. Electronic scale plays an important role in every aspect of economy, such as measurement management, product quality control, material cost consumption and other fields.

Electronic hopper scale is not continuous cumulative automatic scale, so no personnel need to intervene when weighing, hopper scale can automatically add and unload materials according to the set procedure. Because the amount of feeding ingredients can not only directly affect the furnace condition can be smooth smelting and smelting product quality is up to standard. It also plays a very important role in reducing production costs and energy saving, so it is very important to improve the accuracy of hopper scale and reduce the failure rate at this time.

Hopper scale is composed of weighing display panel, weighing body, weighing sensor and junction box. The more common fault of electronic hopper scale is that the instrument panel does not display or the displayed value fluctuates and the error is very large.

When the hopper scale fails, the external factors can be excluded. Because the mechanical failure of the scale body is generally the scale body is supported by the object, the scale body deformation or limiting device fault, signal transmission fault and weighing sensor support head fault and so on.

Hopper scale must be preheated before use, preheating time is a little longer, the accuracy is high, but each batching scale is different, so the preheating time is different. Depending on the ambient temperature, it is necessary to extend the preheating time in special cases.
