AI Technical Summary

Technical Problem

In the pursuit of high precision and miniaturization, existing weighing sensors, especially electronic balances with a precision of one ten-thousandth, suffer from problems such as large size, difficulty in narrowing the width span, and soft and easily deformable materials of the conductive components, making it difficult to maintain flatness.

Method used

The base, support frame, and parallel conductor adopt a split structure, which are processed and formed separately. The materials selected are harder than those of the base. The lever and magnet assembly are set inside the base. The parallel conductor adopts a thin frame structure to reduce the width span and improve flatness.

Benefits of technology

This results in a smaller overall size and lighter weight for the weighing sensor, and the conductive components are easier to process into a flat top surface, meeting high precision requirements.
