LINEAR COMPENSATION APPARATUS AND WEIGHING SYSTEM FOR ACCURATE WEIGHING AND MEASUREMENT OF FINE MATERIALS

The present invention provides a linear compensation apparatus and a weighing system for accurate weighing and measurement of fine materials. The linear compensation apparatus comprises a weight loading mechanism, and the weight loading mechanism comprises a bearing plate, a drive apparatus, and a measuring weight, wherein the drive apparatus is mounted onto the bearing plate, the measuring weight is connected to the drive apparatus, and the measuring weight is hoisted or lowered by the drive apparatus to apply loads to or reduce loads from the bearing plate. The linear compensation apparatus and the weighing system for accurate weighing and measurement of fine materials in the present invention can greatly reduce device costs and labor costs in a batching process, save time and effort, have no risk of cross-contamination, and achieve automated production operation.
