Скачать или смотреть What does a Checkweigher Do?

Thanks for watching the Checkweigher Glossary video. Checkweighers are designed to obtain information to help you meet your weight-related product inspection needs. To get the most out of your equipment—and your product—it is important to understand a few key terms.

An in-motion or dynamic checkweigher weighs products, then rejects or accepts them based on preset weight zones. In-motion checkweighers automate processes, increasing speed and productivity while decreasing operator intervention. These systems provide a 100% inspection rate and reduce human errors.

Meanwhile, a static checkweigher is designed to verify product weight to be within a preset range or target, but it requires an operator to move product on and off the platform. A static checkweigher requires very little maintenance and there is no process control to service. This type of checkweigher also has a much lower initial cost. Infeed and outfeed conveyor belts move products through an in-motion checkweigher and along a production line. Since checkweighers are typically integrated into a pre-existing production line, conveyor belts can often be customized to fit your application needs.

Load cells are inside these checkweighers and that's how the weight is measured. Load cells come in various types, but they all serve the same purpose: accurately measuring weight on a scale. When weight is placed on the scale, the load cell takes an analog measurement and converts it to a digital output at the load cell, junction box, or scale indicator. Load cells are typically constructed of either aluminum or stainless steel, depending on the application requirements, and are located underneath the scale top, which is integrated into the conveyor.

The indicator, or controller, displays advanced weight functions and serves as the command center for calibrating and operating the checkweigher. Indicators show real-time monitoring of preset weight zones and allow viewing and printing of user, product, statistic and parameter reports.

Have you ever wondered what net weight or gross weight means? Gross weight is the total weight of the pack or container and its contents, while tare weight is the weight of simply the package or container. The net weight is the weight of just the package or container’s contents. Weight zones are the ranges of preset target weights that determine whether a product is accepted or rejected.
