Research on calibration technology of computerized combined scales
The computer combination scale has the advantages of high weighing accuracy and fast weig-hing speed,especially suitable for quantitative packaging weighing of bulk materials with large particle mass or uneven particle quality.The accuracy of the measurement of the net content of quantitative pack-aged goods is related to the legitimate rights and interests of consumers.At present,most of the commonly used quantitative packaging commodity production equipment adopts materials and control scales(indi-rect comparison method)for measurement calibration,which is suitable for gravimetric automatic loading scales[1],and lacks the method of computer combination scale measurement calibration.According to the combined weighing principle of computer combination scale,this paper develops a set of loads that simu-late the shape and quality of common materials,accurately assigns the simulated load through high-accu-racy weights,and can realize static calibration and dynamic measurement calibration of computer combi-nation scales,and proposes a calibration method for computer combination scales,which can reduce the uncertainty in the measurement process.
