Hi all - I bought a load cell for part of a propeller design rig I'm building, and I'm stuck trying to work out how to hook it up. The doc reads like this (eBay item 350651562527):-
Rated Output 1.0946mV/V
Input Impedance 410±10Ω
Output Impedance 350±3Ω
Excitation Voltage 5-10V DC
However, my LabJack U12 is rated like this:-
8 Single-Ended, 4 Differential 12-Bit Analog Inputs
±10 Volt Analog Input Range
So I'm needing some way to convert the mV load cell output into the ±10 V range my instrument expects to read.
Can someone help, or point me at "nubie compatible" instructions for this kind of thing? I'm good with the software stuff (I even wrote the open-source perl drivers for the U12), but I'm out of my expertise zone on this voltage-conversion problem.
Alternatively - if anyone knows a different instrument that will let me read a bunch of these things at once into a PC via USB or RS-232 - that too would suffice.
