摘要
本文给出自动衡器的主要误差源和最大允许误差的定义。衡器误差的测量均为抽样测量,抽样测量分为计量抽样和计数抽样。R87号国际建议的负偏差数属于计数抽样。最后对近年来OIML组织对皮带秤用传感器选用的要求做了说明。
Firstly,this paper give the definition of main error sources and maximum allowable error of automatic weighing instrument.The measurement of weighing instrument error is sampling measurement,which is divided into measurement sampling and count sampling.The negative deviation of R87 belongs to sampling by attributes.Finally,we explain the requirements of OIML organization on the selection of sensors for belt weigher in recent years.
