Are there issues with using load cells near the ends of their range?
Are there issues with using load cells near the ends of their range?
(OP)
Feel free to correct my vocabulary here (not sure if spectrum is the right term).
Are there issues with using a load cell in the lower part of its measurement spectrum? For instance, a load cell rated for 0 N to 2500 N, is it less accurate or precise in the 0 N to10 N range than it is in the 1000 N to 1010 N range?
I understand it would not have the same resolution as a 10 N load cell itself; I am just wondering if there is reason to avoid using the load cell at the extremities like this.
Also, are load cells linear? I was thinking I could determine the resolution of a load cell by dividing its range by its bit width, would this be correct?
For instance, a 0 N to 1000 N load 16 bit load cell would have a resolution of 1000 / 2^15 ... ?

Your problem will be noise. You will likely need to take many samples and average them to see load changes in the one Newton Range.
