Easy to understand (instrument) —— Scale
Thread Content
I wrote these thoughts inspired by \"An Easy Understanding of PID.\" Science originates from life yet transcends it; we are all confused by theoretical problems, but in fact, real-life examples can explain science very well! The weighing process of a scale is essentially the process of someone buying goods! Xiaoyun went to Boss Chen to buy apples. The weight of the scale itself plus the dust on it constitutes the dead weight. The 10 jin that Xiaoyun wanted to buy is actually the target value that needs to be set. The process of Boss Chen placing the apples on the scale is what constitutes loading the scale; the sensor acts like a counterweight. Everyone else, please add more details!
Haha, if apples are added quickly, it’s called rough feeding; if they’re added slowly, it’s called fine feeding. It’s similar when picking apples: coarse cutting and fine cutting. The scale used by the poster is really outdated – it’s still a rod scale. Aren’t all scales in grocery stores and street vendors nowadays electronic?
Reply to 2# *asha6688: I feel that many of today’s electrical instruments use complicated terminology, just like the archaic literary language of old; the wording is convoluted and hard to understand. It’s just a scale, yet how many people really understand how packaging scales work? Some are controlled by PLCs, while others are controlled by microcontrollers. . . . . . It wasn’t installed by myself; it really takes time to understand it!
It’s hard to understand; I don’t get it either. Does the original poster have any materials?
