High accuracy sensitive instrument

Abstract

The invention discloses a high accuracy electronic scale. The high accuracy electronic scale mainly comprises a support iron plate, two springs, a sliding rheostat, a fixed value resistor, an ammeter,a switch, a power supply and leads, wherein the support iron plate is connected with the sliding rheostat, the springs are connected with two sides of the support iron plate, the ammeter is connectedwith the sliding rheostat, the fixed value resistor is connected with the sliding rheostat, the switch is connected with the power supply, and other parts are connected through the leads. The novel simple self-made electronic scale is constructed. When weight of an object is weighed, the switch is firstly closed; when no object is weighed, the resistance value of the sliding rheostat is quite great, and the current of the ammeter is quite small; when the object is placed on the support iron plate, under the action of pressing, the resistance value of the sliding rheostat is changed, the current becomes greater; through the change value of the current, mass of the object can be conveniently acquired, the electronic scale is convenient and fast, accuracy is high, and the electronic scale isgood for the life of people.

Description

technical field [0001] The design of the present invention is an electronic scale, especially a high-precision electronic scale. Background technique [0002] With the development of society, people's living standards are constantly improving, and people's lifestyles are also changing. People hope that problems in life can be solved more quickly and work more efficiently. The status of electronic scales in life is getting higher and higher, and people need to use electronic scales everywhere in their lives, but the electronic scales on the market are not only cumbersome, but also have low accuracy, which often makes people complain. In order to adapt to the development of the market, I think it is necessary to invent a more accurate and convenient electronic scale, which can better solve life problems for people. Contents of the invention [0003] The problem to be solved by the design of the present invention is to provide a high-precision electronic scale. Its producti...
