What are the factors that affect the accuracy of the belt weigher?
1. Carrier:
The carrier of the belt scale is commonly known as the scale frame and platform. The filtering (average) effect of suspended carriers is better than that of parallel bars. To truly judge the advantages and disadvantages of the belt weigher carrier, it is still necessary to analyze the structure and mechanical characteristics of the carrier.
2. Stress analysis:
The weighing process of the belt weigher is special. The weight of the weighed material is weighed by the belt of the belt conveyor through the carrier (scale frame). Therefore, in addition to measuring the weight of materials, the final cumulative weight also needs to measure the speed of materials passing through the carrier.
3. Speed sensor:
Also called displacement sensor. As the belt scale is used to weigh the cumulative total amount of materials transported through the conveyor, in addition to weighing, it is also necessary to measure the speed of the weighed materials. Therefore, the accuracy and stability of the speed sensor are also crucial to the accuracy of the belt scale, and the stability is more important.
4. The conveyor belt is too long,
It is also an important factor affecting the measurement accuracy.
The above information is compiled by the belt weigher manufacturer. I hope it can give you some help.
