Explanation and questions about the control principle of weightlessness scale

Regarding the weightlessness scale, what is involved below is mainly related to some difficult problems, which have not been before. The purpose is for everyone to learn more about the product, so that they can know and master more. Furthermore, you can apply what you have learned well and make learning more meaningful and valuable. Question 1: What is the working principle of the control system of a weightlessness scale? The working principle of the weightlessness scale control system is as follows: its control system continuously collects the weight signal and calculates the instantaneous flow rate of the material through a certain calculation relationship. Then, compare it with the set flow rate. If there is a deviation, output the deviation control amount, and through some methods to make the two flow rates achieve dynamic consistency, so as to meet the control requirements. Question 2: If the weightlessness scale weighs different powders, is the screw used for it the same? If the weightlessness scale weighs different powders, the screw used is different.
