Analysis and Evaluation of Uncertainty of Error in General Pressure Indicating Value

JI Yu* DONG Ji-guo LIU Xiao-yu （Aksu Regional Metrology Calibration Institute）

Abstract： A general pressure gauge isa measuring instrument for detecting the size of pressure values， with the advantages of practicality，economy，andaffordability，andtherefore itis widelyused.According to JG52-2013， Elastic Element Pressure Gauges， Pressure-Vacuum Gauges and Vacuum Gauges for General Use，a 0.4-grade precision pressure gauge isusedasa standardinstrument forcalibrating l.6-gradegeneralpressure gauges toevaluate the uncertaintyofthe measuredvalue ofgeneralpressure gauges，andprovide reference forenterprisesandinstitutions to develop new measurement standards and compare work.

Keywords： general pressure gauge， indication error， measurement uncertainty

一般壓力表是一種指示壓力大小的儀表，通過(guò)指針直接顯示壓力大小，主要應(yīng)用在安全防護(hù)領(lǐng)域，例如測(cè)量鍋爐壓力和管道壓力等，廣泛被應(yīng)用于石油、機(jī)械等領(lǐng)域。（剩余4167字）
