In-motion vs Static Checkweighing
An in-motion (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.
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 lower initial cost.
Conveyor Belts
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
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.
