वजन पैमाने किसी वस्तु के वजन या द्रव्यमान को निर्धारित करने के लिए मापक यंत्र है
The load cell is a transducer that converts force signals to an electrical signal. In load cell mounted strain gauge (retable resistance).The load cell work principle of Wheatstone bridge.
Weigh scale work with many types of devices. Like
1 load cell
2 Microcontroller, microcomputer
3 AD controller
4 Key bord
5 Display
1.Description of Load cell
In many load cells, we see four-wire. Two-wire for Input voltage(5-12) and two-wire for output(in mv.
2.Description of Microcomputer/microcontroller
Microcomputer/microcontroller Is a programming ic (reprogramming IC) .this IC convert AD signal to digital signal and controller keypad, display,.
3.Description of AD Controller IC
AD controller is analog to digital converter. This is converts analog (electrical) signals to digital signals.
4. Description of key bord
Key bord use to operate the weigh scale like Tare the weight and entre the programming, change to data programming.
5.Description of Display
When we put the weight on the platter then load cell send signal to AD controller then AD controller send signal to Microcomputer and then Microcomputer send Digital signal to Display the weight.
In weigh scale use 3 type of display
1. LED Display (Light Emitting Diod)
2.LCD Display (Liquid Crystal Display)
3. VFD (Vacuum Fluorescent Display)
