Hi,

I'm considering trying this tutorial to learn more about loads cells for a project I have in mind.

I would appreciate a couple of pointers before getting started.

1. If using the FX1901 load cells, what the maximum weight that can measure?  Found a online converter that states 200 lbf equates to 90kg - does this sound about right?
(http://www.convertunits.com/from/lbf/to/kg)

2. What the correct logic in you wanted to add more than one load cell in order to increase the max weight measureable?  Would you just need another amplifier and then combine the two readings from to analog inputs?

datasheet I found says: 10 - 100 lbf Ranges  (4,5..45kg)
If use is a bathroom scale, each cell should take more load, else load(person) need to be placed
very close to center of scale (with a cell in each corner)
