Dustproof balance

Abstract

The invention provides a dustproof balance. The dustproof balance comprises a bottom shell, a main board, a sensor, a weighing plate support, a leveling bolt, a power supply, a weighing plate, an upper cover and a display screen which is connected with the main board. The dustproof balance disclosed by the invention is reasonable in structure, simple and rapid in weighing process and high in accuracy and has the characteristic that: a dustproof cover is arranged on the upper cover, so dust can be effectively prevented from contacting the upper cover and weighing accuracy is enhanced.

Description

technical field [0001] The invention relates to a balance, in particular to an electronic balance with dustproof function. Background technique [0002] The balance is an ancient weighing instrument, which was produced earlier. By the late Spring and Autumn Period, the manufacturing technology of balances and weights had been quite sophisticated. Use bamboo slices as beams, silk threads as buttons, and a copper plate hanging from both ends. Later, because it was troublesome to weigh heavy objects with a balance, it was changed to "Quan", and the balance was only used when weighing small objects. With the advancement of science and technology, the balance, an ancient tool, has also been greatly developed. Differential sign balances, rack balances, resistance balances, single-pan unequal arm mechanical balances, electro-optic resistance balances, electronic balances, etc. have appeared. The types of materials to be measured are becoming more and more abundant, the accuracy o...

AI Technical Summary

Problems solved by technology

Since the balance is a precision instrument, the accuracy of an ordinary electronic balance can reach one thousandth, or even one ten thousandth, so the dust adsorbed on the surface of the balance weighing pan may directly affect its weighing accuracy
