Abstract: This paper describes a validation of a combinatorial calibration technique based calibration procedure for strain-gauge amplifier calibration. The deviation between two strain-gauge amplifiers at calibration using the combinatorial technique is compared to the deviation between the same two amplifiers at calibration on a force calibration machine as a transducer-amplifier chain under unchanged conditions, serving as an amplifier linearity comparator. This enables the validation to be confirmed with a suitable expanded measurement uncertainty of 3 nV/V.Keywords: strain-gauge amplifier, calibration, combinatorial technique, validationPublished in DiRROS: 21.08.2023; Views: 1432; Downloads: 586 Full text (438,26 KB)This document has many files!
