  • Hi, Quailb!...So if I understand correctly, you placed 2 of these load cells in parallel (white-white(Vin), black-black(grnd))and placed the diff. voltage of the red wires into the AD620 (gain 1000) and the output of the aplifier into an RC filter to eliminate some noise, right?...My question would also be how did you physically managed to measure the weight of a pen?...I mean, did you just placed the pen on top of one of the 2 load cells you used or did you used something like a plate on top of both the load cells and placed the pen in it? In other words...are both load cells used for measuring or do you measure just with one and the other is just for compensation?...Thanks for your reply :)

No public wish lists :(
