20.500.12556/DiRROS-18623 Improving uncertainty of strain gauge bridge standards The article proposes a procedure for calibration of strain gauge bridge standards with improved relative calibration uncertainty. In contrast to a typical calibration with voltage ratio standards or comparison calibration with other bridge standards, the proposed procedure uses a calibrated reference bridge amplifier, additionally evaluated using combinatorial calibration technique to improve its calibration uncertainty. The resulting uncertainty of ratio steps referenced to zero ratio step is lower than the traditional uncertainty achieved through direct independent traceability to mVV−1 ratio values. The proposed procedure enables direct application of the calibrated bridge standard values with low relative uncertainty for calibration of bridge amplifiers, without the need for additional combinatorial evaluation of each individual bridge amplifier. voltage ratio linearity check bridge standard calibration napetostno razmerje preverjanje linearnosti etalon za mostič kalibracija true false true Institute of Physics Publishing Angleški jezik Slovenski jezik © author, 2018 Neznano 2024-04-05 08:14:47 2024-04-05 08:34:40 2024-04-09 03:40:09 0000-00-00 00:00:00 2018 0 0 Nasl. z nasl. zaslona; Opis vira z dne 15. 2. 2019; Št. članka: 042035; Str. 1-4 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2018-08-01 621.317 1742-6596 2429287 12256084 https://doi.org/10.1088/1742-6596/1065/4/042035 0 7085b256-f30b-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25416 RAZ_Hiti_Miha_2018.pdf RAZ_Hiti_Miha_2018.pdf 1 1D3E5F6BC744041A96F10C94DA06BA91 f5676a157418d9bf90eb4e1fd8c542b075daf474cc3bf54a3a785fcfdc0003d4 04b079ef-f310-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25422 Zavod za gradbeništvo Slovenije 0 0 0
