Abstract: Industrial analyzer is a measuring instrument used for measuring ash content, volatile matter, and moisture in coal. This article analyzes and evaluates the uncertainty of the measurement results of industrial analyzers, and analyzes the reasons for the uncertainty, aiming to provide reference for metrology personnel in the operation, use, and evaluation of industrial analyzers.
Keywords: industrial analyzer; metrological verification; indication error; uncertainty
0引言
煤的灰分與煤的發(fā)熱量息息相關(guān),灰分不僅是煤炭質(zhì)量評定中非常重要的指標之一,也是煤炭定價評級、按質(zhì)論價的評定標準之一。(剩余3454字)
