Could anyone here (especially @joeyd999) tell me if the following reasoning is correct? Thanks in advance.
Say I'd like to measure a weight of up to 100Kg, with a 100Kg capacity load cell.
This load cell has an hysteresis of 0.02% of its rated output, and so it has a maximum theoretical accuracy of 20 gr, even with the best available ADC and perfect calibration.
Say now that I replaced said 100Kg load cell with five 20 Kg Load cells (never mind for the moment how I'd manage to distribute the weight evenly).
If each 20 Kg load cell also has an hysteresis of 0.02% of its rated output, then it would mean that the hysteresis value for this load cell is 4 gr. And that the maximum theoretical accuracy attainable is five times better than the single 100 Kg load cell.
Assuming meticulous calibration, would a system that simultaneously uses five 20Kg load cells (each with its own independent ADC) in parallel to measure a weight of up to 100Kg have a five fold improvement in accuracy compared to a single 100 Kg load cell?
