一、应用中出现的数据异常判断及处理某单位的电子汽车衡(简称A衡)为供货称量衡器,主要用于称量汽车罐车运输的液体物料,在检定有效期内使用,其称量范围为0~100t,分度值为20kg,传感器6只。在应用中,相关方反映A衡称重出现异常数值。需方电子汽车衡(简称B衡,参数同A衡)作为复检衡器,B衡复检的结果大多数为负偏差,且数值较高。1.数据异常情况判断A、B两台汽车衡相距较远,称量过程相反,在长途运输中存在一定的燃料消耗、添加,引起皮重变化,同时存在液态物料的损耗,复核数据的不确定性增加。为此,选用A衡附近一
First, the application of data abnormalities to determine and deal with a unit of electronic truck scale (referred to as the A-scale) for the weighing weighing equipment, mainly used for weighing the tanker transport of liquid materials used in the validity of the test, the weighing Range of 0 ~ 100t, indexing value of 20kg, 6 sensors. In the application, the relevant parties reflect the abnormal value of weighing A. Demand-side electronic truck scale (referred to as B-scale, the same parameters with the A-scale) as a re-examination of the instrument, B-level retest results most of the negative bias, and higher values. 1. Data anomalies to determine A, B two truck scales are far apart, the weighing process on the contrary, in the long-distance transport there is a certain amount of fuel consumption, add, causing the tare weight changes, while the loss of liquid materials, review data is not Certainty increases. To this end, the selection of A near a
