What do "eccentric load" mean and "limit bending moment" mean?

Explanation of the terms "limit bending moment" and "Eccentric Load"

The term "eccentric load" actually comes from so-called single-point load cells. These are the load cells that are built into the fruit and vegetable scale: There a load cell is located under the weighing plate. This load cell may be loaded "eccentrically", at the edge of the plate, without causing an unacceptably large error.

One can convert this eccentricity into a corresponding bending moment. But the allowable eccentricity is just more descriptive for scales.

With force sensors, one likes to specify a permissible bending moment. The permissible bending moment at which no damage occurs is called the "limit bending moment". However, this does not say anything about the measurement error that could occur. This is initially a purely mechanical statement.

For force sensors, one enters e.g. indicates one error per Nm. With scales, one likes to give an error per mm of eccentricity.
