Relative reversibility error
In practical applications, the linearity error can be substantially reduced by competently selecting the transducer's calibration range. If a force transducer with a nominal (rated) force of 100 kN, e.g., is used at 50 kN, it can bThe relative reversibility error is the difference between the force transducer's characteristic curve with increasing and decreasing force. HBM specifies the maximum deviation. In addition, the data sheet specifies the force range in which the relative reversibility error has been determined. The value is specified in fractions of the nominal (rated) force (e.g., 0.4 Fnom = at 40% of the nominal (rated) force).
The relationship used for linearity applies analogously; with reference force transducers, the relative reversibility error is specified relative to the actual value.e calibrated in this range. This halves the error, since computation of the linearity error now can be based on the calibration range.
