Temperature Sensing with RTD, Thermistor, and ThermocoupleBridge Sensing for Pressure, Strain, and ForceWeigh Scales
The load cell is a wheatstone bridge. Not sure why you'd be adding resistors?
you might not be able to do this without some kind of amp.
what about a cheap rail2rail opamp?e. g.: ISL28130CEZ ( http://www.digikey.com/product-search/en/integrated-circuits-ics/linear-amplifiers-instrumentation-op-amps-buffer-amps/2556125 )wired up as an amplifier...http://en.wikipedia.org/wiki/Opamp#Non-inverting_amplifier
maybe u should use this topologyhttp://en.wikipedia.org/wiki/Operational_amplifier_applications#Differential_amplifierfor that bridge...?
can u show us a picture of ur assumptions about the internals of that "load cell"?
