We should know a lot about the so-called traditional weighing equipment. For example, the hook scale used in our rural areas, one weighing pole with one weight, mainly uses the principle of leverage and the balance of force to measure weight. This principle is used in traditional weighing equipment. It is widely used in medium, such as scales, which use increasing or decreasing weights to test the weight of objects. With the progress of the times, traditional weighing equipment has gradually shown its limitations and shortcomings due to the needs of economic life. Large and very large objects need to be weighed, which is a waste of manpower, and weighing is also very complicated. Like some small and miniature objects, traditional weighing instruments cannot measure at all and their accuracy is too low.
The electronic scale is a kind of weighing instrument with high precision and wide measuring range developed to meet the needs of economic and social development. The main components of the electronic scale are divided into three parts, one is the scale body, the other is the sensor, and the third is the display. Its basic working principle is that the object passes through the scale body to make the scale body generate pressure, and this pressure is transmitted to the sensor. The sensitive beam on the sensor will be deformed under pressure. The signal generated by this deformation of the sensor is converted into identifiable data. Then the data is transmitted to the CPU (central processing unit) for calculation, and the CPU transmits the calculation result to the display. The whole process can be summed up in one sentence, which is to convert force into identifiable electrical signals, and then calculate the electrical signals into weight unit numbers.
Electronic scales are not only used for weighing, but can be divided into pricing scales, counting scales, and weighing scales according to the scope of application.
This is my general understanding of electronic scales.
