Weightometer Calibration Accuracy (3 replies)
Please join and login to participate and leave a comment.
Hello everyone, what methods do you use to verify your conveyor belt scale’ accuracy of calibration?
I'm familiar with belt cuts as it is the only method i have had practical experiences with. Recently, we did a 30 meter belt cut on a 700 meter length belt. The belt reading showed about 35% reduced tonnage relative to the belt cut. This is a huge difference and I'm just wondering what you think could be the problem.
I heard some compare a truck weight with material in other weighing system & others use a weighted wheel riding on the belt for a given length belt then calculate the total and compare with scale weight.
What is the best method? How do you calibrate a weight-scale and check its accuracy?
