概述
Sartorius PR5510称重控制器，是电子衡器中显示被称物的质量和称量状态的仪表。工业中的过程控制是指以温度、压力、流量、液位和成分等工艺参数作为被控变量的自动控制。就一般而言，管理中采取的控制可以在行动开始之前、进行之中或结束之后进行，称为三种控制模型。第一种称为前馈控制或预先控制，第二种称为过程控制或同期控制，第三种称为反馈控制或事后控制。
The BATCH-X4 is a weighing controller with internal recipe handling to allow automation of batching, manual additions and process steps.
Sartorius X4是一款内置Recipe操作，实现配料、人工添加和工序自动化的称重控制仪表。
应用
In many batch processes, different kinds of raw material are processed into intermediate and end products. From raw material storage area they are dosed to the production and processed in different steps like heating, cooling, stirring etc. The production steps and the raw materials with its set-points are described in a recipe. The Stand-alone batch controller BATCH-X4 meets the requirements of small batch applications in different industries, like food industry, chemical industry or building material industry.
在很多配料过程应用中，不同种类原材料被加工成中间或者最终产物。在原料库中，原材料被喂进料仓，然后经过不同步骤加工，加热、冷冻和搅拌等，生产步骤和原材料设置点都可在控制器里描绘出来。作为一款独立配料控制器，X4满足不同行业所有小型配料应用的需求，例如食品行业，化学行业或者建筑行业。
