Key terms commonly used in automatic check weighing scales

Conveyor belts

Conveyor belts move products into and out of the checkweigher on the production line. Checkweighers often fit into existing production lines. You can tailor conveyor belts to meet your needs.

Load cells

Load cells vary in type, but they all measure weight with precision on scales. When you put weight on the scale, the load cell measures it. Then, it changes the measurement into a digital signal within the load cell, junction box, or scale indicator. Load cells are made from aluminum or stainless steel in most cases. The choice depends on what the application needs. The system places them under the top of the scale, fitting them into the conveyor.

Weight indicator

Indicators or controllers show advanced weighing features. They act as the command center for calibrating and operating checkweighers. Indicators show real-time monitoring of set weight zones. They also let you view and print user data, product info, stats, and parameter reports.

Checkweigher accessories

Checkweighers offer many optional accessories, like reject devices, alarms, and barcode scanners. These tools keep your production line running smoothly. They also boost the efficiency of check weighing.

Gross weight, tare weight and net weight

Gross weight includes the total weight of the package and its contents. Tare weight is just the weight of the package or container by itself. Net weight is only the weight of the contents of the package or container.

Weight interval

A weight interval is a set range of target weights. It helps the decision-makers decide if they accept or reject a product.
