Dear All,
I am having problem little bit about platform load weighing system.
I have 2 design. One of them will have 2 load cell and other one will have 4 load cell. I am using INA129P as amplifier.
I know that I need junction box to get accurate weighing for load cells. but when I make search on google, I did not find any helpful information about that. some of them says, connect them in series, but most of the products has multiturn potentiometer on connections. Is there any reference circuit or information to make a junction box reference circuit?
Also, load cell has drifts and they can be adjust with offset trimming on op-amp. Which is the better, offset adjust on Load cell signal side with pot, or offset adjust on op-amp reference input?
Thanks
