摘要： An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.

摘要： Accurate weighing and measurement of fine materials is provided by a linear compensation apparatus and a weighing system. The linear compensation apparatus has a weight loading mechanism (10) with a bearing plate (11), a drive apparatus (12), and a measuring weight (13). The drive apparatus is mounted onto the bearing plate, the measuring weight is connected to the drive apparatus, and, by hoisting or lowering the measuring weight with the drive apparatus, loads from the bearing plate are adjusted. The linear compensation apparatus and the weighing system 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.
