- Abstract:
- Load cells (LC) used in weighing instruments under legal control can be tested separately as a module according to the OIML recommendation R60 (R60). R60 prescribes the principle metrological static characteristics and static evaluation procedures for LCs used in weighing instruments for legal metrology. Since the 1st revision of R60 published in 2000 further developments of LCs lead to new experience and requirements.
This paper presents abnormalities of LCs observed on single test patterns like the influence of the force introduction, eccentricity effects, effects of excitation voltage variations, drying effects of the strain gauge sealing but also effects of temperature gradients that may strongly affect the metrological characteristic of LCs.
The effects have to be discussed and taken into account for a planned 2nd revision of R60 if needed. - Keywords:
