About Conveyor Scales

Conveyor scales are a type of weighing system that are used to accurately measure the weight of products or materials as they move along a conveyor belt. These scales are widely used in many industries, including manufacturing, mining, and logistics, as they provide an efficient and automated way to measure large quantities of products or materials.

The use of conveyor scales offers some benefits. Firstly, they provide accurate and reliable measurements, which can help to ensure that products or materials are weighed correctly, and that the correct amount is being produced or shipped. Secondly, they offer an automated solution, reducing the need for manual weighing or counting, which can save time and improve efficiency. Finally, conveyor scales can be integrated with other systems, such as barcode scanners or inventory management software, to provide a comprehensive solution for tracking and managing products or materials.

There are several different styles of conveyor scale which all operate in different ways and for different purposes. The two major distinctions to be made is the difference between a traditional conveyor scale and a checkweigher.

The most significant difference between these two pieces of equipment is what each does with the data it collects. A traditional conveyor scale simply collects the weights of the items being conveyed through it. This data can then be sent to a different piece of equipment to take an action.

A checkweigher will not only weigh the items being conveyed through it, but it will also compare the weights to your preset weight standards and then allow an action to be taken, such as stopping the conveyor or allowing any items with discrepancies to be diverted.

Conveyor scales can be an invaluable asset to any conveyor system, no matter the size. With a used conveyor scale or checkweigher from American Surplus, you can maximize your efficiency by avoiding the need to individually weigh items for quality control or shipping. We even have a selection of label makers to fully integrate the whole process. Speak with a member of our sales team to learn more about our current selection of conveyor scales, as well as our full array of conveyor accessories.
