OPamp

Chagrin:
The load cell is a wheatstone bridge. Not sure why you'd be adding resistors?

I need to add resistors as a "dummy" load cell since the ones I have aren't "full-bridge" I could also combine 2 or more cells into a bridge but that seems like a waste of expensive parts to me.

Chagrin:
you might not be able to do this without some kind of amp.

That's why I started this topic, it's less about the cells and more about the OPamp
