4 Types of Belt Scales

Belt scales are a practical addition to a conveyor belt system to help weigh the materials being carried. Aggregates and mining are two industries that make use of the electronic belt scale system. Plus, most of the weighing devices are compact in size which means it is easy to install on most existing conveyor belts.

Monitoring the weight and amount of rock, fish, wood chips, or other material that flows across the belt is essential in a variety of situations for its ability to gauge the consistency and accuracy of the output.

There are several types of belt scales to match the specific needs of the different industries and environments. Here are four of the most popular types of belt scales:

Single Idler

The most cost-effective method to weigh material is the single idler scales. This is a practical option for tracking low-cost inventory and is easily mounted to portable equipment.

Multi Idler

For the more expensive products at a large size and in need of more accuracy, it usually benefits to upgrade to the multi idler scales. This type of scale has the ability to operate on the fast-moving belts while still being able to provide highly accurate readings of the weight.

Stainless Steel

The scales manufactured in stainless steel are the most practical option for an industry operating in more corrosive and harsh environments. This type of scale is a practical choice for corrosive manufacturing like fertilizer plants, salt processing, and salt mining.


The preferred scales for high volume are known as in-motion and have the capability to weigh up to 12,000 tons or more. This type of scale can give highly accurate readings and precise control. For ease in reading the weight on the in-motion scales most are designed with an LCD display. Also, a ticket printing system can feature to make it easy to print out the weight of the load that has recently passed the scales.

What are the standard features?

Most of the belt scales come with a variety of standard features to ensure they are simple and efficient to operate. Some of the most common features include an LCD which is usually large and touch operated, the ability to save data using a USB stick, large control keys for easy operation, the ability to connect via wireless technology, and report generation. The ability to produce reports makes it possible to view TPH range values, down time, and graphs.
