I am in need of some assistants, and was hoping that you guys might be able to help. I'm trying to find a suitable OPamp for a 45KG load cell, I've spent the last couple of days surfing the web hoping to find an answer and I sort of did, many of you suggest using the INA125 instrumentation amplifier, but here's the thing, I don't really need an accurate readout.
I'm in more of a need of weight detection than weight measuring, with a resolution of say 25KG. So I was hoping that a more basic OPamp would do. Or perhaps another device altogether if there is such a thing?
I do have some requirements for the amp, I'd like for it to work of 5-9V and have a adjustable gain using a resistor, if the output was fairly noise free.
Thanks in advance.
