| Zusammenfassung | The load cell is the "heart" of a weighing machine. It transforms the force of a weight as a quantity of mass usually into an electric measurable quantity. The load cell determines the accuracy of a nonautomatic weighing instrument (NAWI) at most, this is confirmed by the apportioning of errors in table 7 of the OIML Recommendation NAWI, R76-1. The OIML R 76-1 (Edition 1992, with Amendment1 1994) is the fundamental basic regulation nearly for all metrologic weighing purposes. The regulation for the module load cell, OIML R 60 (Edition 1991) has been developed parallel respectively of the predecessor of the R76 the regulations IR3 and IR28. The test report format for the evaluation of load cells, OIML R 60-Annex got edited in 1993. Nevertheless all technical regulations has to be at least improved to allow and to regulate technical progress. The following part of this lecture will generally describe in brief the R60 and its annex, with some special details but not absolutely completely. |
