Evaluation of measurement uncertainty of indicative error of intelligent transmitterZHANG Hong, CUI Jin-shan 1. Ethylene Complex Instrumentation Workshop of Dushanzi Petrochemical Company, Dushanzi 833600, China; 2. Analysis test Center of Academy of East China Pipeline Design, Xuzhou 221008, ChinaAbstract:This article discussed measurement uncertainty in the calibration of the intelligent transmitter using 744 process calibrator. It based on JJF1059-1999, "Evaluation and Expression of Uncertainty in Measurement" and discussed several major origins of uncertainty in measttrement. Finally, measurement uncertainty of an indicative error of intelligent transmitter was analyzed and evaluated.

Key words:Origins of uncertainty; Assess; Regulator; Error; Expanded uncertainty
