The Factors That Reduce Accuracy in Conveyor Belt Scales

Conveyor Belt system for Package tranfer machineAccuracy is the main requirement for conveyor belt scales. Acme Scale Technologies, a manufacturer of weighing equipment and precision products, agrees that accuracy needs to be repeatable. Problems with accuracy happen every now and then, and there are recurring factors as to why that takes place.

Idlers are Too High or Too Low

Figuring out the proper position of the idler for the weighing device may come as a challenge. This is the biggest problem when it comes to scale accuracy. You need to make sure that the idler isn’t too high above the conveyor or too low underneath. Getting that alignment can be a very hard process. As little as half a millimeter can create a sizeable negative impact on your conveyor.

A tight conveyer belt might bridge over the scale if the weigh idler is positioned too low compared to the other idlers. On the other hand, a weigh idler placed too high will cause the opposite effect. An increase in the belt tension can occur.

Belt Speed is Too Fast

If the conveyer moves too quickly, materials begin to bounce off of the surface. The conveyor belt scale misses the weight if the measuring happens while the material is in the air. Inaccuracy ranges from one to five percent when the belt speeds are greater than six meters per second. This is an issue particularly when high accuracy is required.

Consider consistent material profiling when the bouncing occurs repeatedly. This can help mitigate the rebound’s impact. For an accurate recording of the material, have it placed on the scale for a long period.

Rare Conduct of Calibration

Conveyer belt scales need to conduct the so-called “zero calibration” to determine the weights and forces of everything other than the items that will be weighed. The initial calibration records belt-related weight. When done, the weight will not discount the actual measurements.

The initial calibration may run smoothly but dynamics can change in a jiffy. This means you need to frequently perform calibration to ensure accuracy, repeatability, and linearity.

Accurate readings occurring repeatedly assure you that your conveyor belt scale is doing its job for you. Regularly monitor your scale. In most cases, frequent calibration always helps.
