Single point Load Cell + amplifier test with multimeter

Electrical block diagram




Weighter beginning



Our first prototype construction for load cell.




This project main goal is development of a device for measuring of weight. Roughly, we can divide device on parts containing mechanics and parts containing electronics. Metal base frame, basket, load cell, pneumatic cylinders and electro magnetic vibrators on mechanical side, on electrical side we have bridge transducer and microcontroller.
