Description

Waterproof Electronic Scale{WATERPROOF ELECTRONIC SCALE}

The present invention relates to a waterproof electronic scale. More specifically, it relates to a waterproof electronic balance that prevents liquid from entering the case from the outside of the case to the inside of the case where the weight measuring unit is located using a waterproof ring.

A waterproof electronic scale is a scale in which the weight to be measured is converted into an electrical signal and indicated, and is composed of a balance mechanism and a reading mechanism that incorporates electronic technology. The balance mechanism of the electronic scale is equipped with a zero method that detects the subtle displacement by the load by electrical loads and applies electromagnetic force so that the balance stand is horizontal, and a strain gauge is attached to the elastic block to form an elastic body. There is a load cell type that detects an electric signal proportional to the load by directly applying a load to a load cell that generates an electric signal proportional to the deformation.

In general, large electronic scales are used for over-interruption purposes, etc. Medium-sized electronic scales and small electronic scales are used for commercial and household purposes to measure the weight or weight of a product. Is being used. Electronic scales used for commercial purposes are mainly used in places such as large marts and markets, and in particular, electronic scales used for fisheries are frequently exposed to an environment where water can be introduced, causing a frequent failure.
