美国Rice Lake 820i/820i-4B不仅是一款数字称重显示仪表，同时是一款为复杂自动化工业过程控制而设计、高性能可编程控制器。
称重控制显示仪表接受称重传感器输出的模拟信号，经内部采集处理后，计算并显示出秤体上物料的重量值。对秤体上物料的重量值与设定值的进行比较，如果重量值达到了设定值，控制器就输出控制信号给执行设备。
称重控制是集成了称重和控制功能为一体的装置，同时兼容工业现场总线，例如Modbus，可以和工业现场常用的控制器PLC，DCS等结合使用，方便工业领域的工程师解决工业称重的问题。
Rice Lake's 820i is more than a digital weight display. It's also a high-powered programmable controller for automation of complex industrial processes.
For the most comprehensive combination of function and price, Rice Lake 820i is the instrument of choice. This versatile intelligent model boasts a powerful yet easy-to-use interface that can operate and display up to two scales simultaneously. The 820i allows users to automate formula selection, batch start up, data recall, or any frequently used process. Available in both universal and panel-mount versions.
Built-in software functionality includes programmability for alibi tracking, 25 definable print formats, and multi-range (interval). The RICELAKE 820i also conveniently stores up to 1,000 truck in/out records for recall at anytime and simplifies truck scale data management with six truck modes and keyed tares.
