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。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。

设计

The housing is designed for easy installation into switch cabinets, operating panels or direct at the machinery as a frond-end unit. The bright weight display with 7 digits plus units and status symbols guarantees a good readability even under harsh conditions. Additional two text lines are foreseen each with 20 characters. Under the text lines function keys are arranged. The meaning depends on the application and guides the operator through the menue. The keys have a double assignment. The second level enables the operator to enter also alphanumeric characters. The BATCH-X4 Process Controller enables the connection of an external PC-keyboard to upgrade the operation comfort in case of data entry. Smart Calibration allows scale commissioning without time consuming calibration with test weights.

控制器外壳设计只为能简易安装在配电箱，控制板或者前端单位机械设备上。自带7位数，单位和状态显示的称重显示屏，即使在严苛的安装环境下也能保证优异的可读性。附带的两个文本行可显示20个字符。在不同的应用上，操作者可通过菜单上的功能键设置不同程序。每个键有两重指令，进入第二重指令，使用者可通过按键输入数字和字母字符。不进如此，万一需要数据录入，操作者可用PC键盘连接X4，提供操作舒适性。智能校准功能使得X4无需测试砝码即可进行刻度调试。
