An Auxiliary Device for Large Weighing Mass Comparators

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.
