Claims

[Scope of utility model registration request]

A parent load cell configured to generate an output signal corresponding to the load applied to the force application part, and an output signal provided in the force application part of this parent load cell and corresponding to the load applied to its own force application part. A child load cell configured to generate a load cell, a protection device provided on the child load cell to prevent damage thereof, and a protection device configured to cause the child load cell to have an output signal that is less than or equal to the maximum allowable load of the child load cell. It consists of a comparator that supplies the output signal of the child load cell to the output terminal when it is below a set value, and supplies the output signal of the parent load cell to the output terminal when it exceeds this value,
The maximum allowable load of the child load cell is smaller than the maximum allowable load of the parent load cell, and the error when applying the maximum allowable load to the child load cell is smaller than the error when applying the maximum allowable load to the parent load cell. load cell.
