The operating force [% of Fnom] is the greatest force in the direction of the measuring axis that a force transducer with built-in protection against overload can absorb without changing its metrological properties. In the case of force transducers without built-in overload protection, the operating force corresponds to the limit force. The working force range should only be used in exceptional cases, the force transducer should be calculated so that the maximum working force is not reached.
