Is it possible to read the mV output of a load cell that has a 10vdc excitation voltage with the arduino? If possible I would like to make a 4 channel load cell data logger. The load cells that I want to monitor and log are 2mV/V wired to a summing board which is then wired to a amplifier/indicator. I just want to read the output of each load cell like you would with a voltmeter, but I want to be able to record the mV readings a couple times a second to help diagnose load cell/binding issues.
I was looking at a few of the load cell amplifiers, like the HX711, I liked the resolution that it offers and that they are readily available in breakout board form and they are relatively cheap through sparkfun and various other places online. I thought maybe I could wire only the output from the load cell into the amplifier but after a google search I found out that due to the excitation voltage I would fry it if I did that.
