An Uncertainty Analysis of Fluke Calibration Fused-Quartz Bourdon Tube Pressure Products

Abstract

The forced-balanced fused-quartz Bourdon tube (QBT) technology is a proven pressure measurement method, which has been used in the metrology field for over 50 years. In the summer of 2010, Fluke Calibration acquired Ruska Instrument Corporation from General Electric’s Sensing and Technologies division which added this unique, high-performance pressure measurement technology to the Fluke Calibration family of pressure products. The celebrated pedigrees in Fluke Calibration’s pressure coterie that employ QBT technology are the 7000 Series pressure products. 7000 Series pressure controllers and indicators, descend from a heritage of unmatched performance and residence in the metrology community. This paper aims at explaining the unique facets of QBT technology, basis of operation and the uncertainty classes available.
