一种应用于大称量质量比较仪的辅助装置研究

An Auxiliary Device for Large Weighing Mass Comparators

大称量质量比较仪在日常使用过程中常常会出现数据波动大、准确度降低以及传感器易损坏等情况。经研究发现,质量比较仪在使用过程中,其对应砝码吊装方式的应用会对质量比较仪的使用产生很大影响,在传统吊装方式中,砝码对质量比较仪台面会产生很大的冲击力,这是导致质量比较仪使用效果不佳的主要原因。为解决上述问题,设计了一款质量比较仪辅助装置,并对其使用效果进行分析,研究发现该装置的应用能大大提高称量的重复性,降低偏载产生的测量误差,数据漂移更小,精确度更高。

In the daily use of large weighing mass comparator,there are often large data fluctuation,reduced accuracy and easy damage of sensor.It is found that during the use of the mass comparator,the application of the corresponding weight lifting method will have a great impact on the use of the mass comparator.In the traditional lifting method,the weight will have a great impact on the table of the mass comparator,which is the main reason for the poor use effect of the mass comparator.In order to solve the above problems,an auxiliary device of mass comparator is designed,and its application effect is analyzed.It is found that the application of the device can greatly improve the repeatability of weighing,reduce the measurement error caused by eccentric load,reduce the data drift and improve the accuracy.
