Background

The electronic scale is a kind of weighing apparatus, which is a tool for measuring the mass of an object by utilizing the law of huiche or the principle of lever balance of force, and can be divided into three types, namely a mechanical scale, an electronic scale and an electromechanical combination scale according to the structural principle. The electronic balance is mainly composed of three parts of a bearing system (such as a scale pan and a scale body), a force transmission conversion system (such as a lever force transmission system and a sensor) and a value indicating system (such as a dial and an electronic display instrument). The working principle of the existing electronic scale is as follows: when an object is placed on the scale plate, pressure is applied to the sensor, the sensor is elastically deformed, so that impedance changes, excitation voltage changes, a changed analog signal is output, the signal is output to the analog-to-digital converter through the amplifying circuit, the signal is converted into a digital signal convenient to process and is output to the CPU for operation control, and the CPU outputs an obtained result to the display for display. But its pan of balance above the current electronic scale is generally fixed on the electronic scale base through simple bolt or other modes, and after long-time the use, it generally can produce certain not hard up in the pan of balance, and it can influence the accuracy of weighing result in the pan of balance that is in not hard up state, and especially to the accurate article of measuring result, the accuracy of its weighing result is just more important.
