A Weight Indicator to Customize Your Process 

To gain a competitive advantage in today's fast-paced business environment, you need cost-effective solutions that not only optimize your processes but also provide an intelligent, flexible migration path. Introducing the 820i Rice Lake programmable weight indicator/controller. The 820i revolutionizes basic instrumentation programming, allowing for more cost-effective maintenance and programming support. Unlike many programmable indicators, the 820i features an intuitive user interface that allows the user to automate formula selection, batch start, data recovery, or any frequently used process at the press of a button. With the 820i on board, increasing the accuracy and improving the efficiency of any weighing process has never been easier. 


In any batch dosing application, it is a challenge to provide accurate, quality products, and at the same time try to reduce costs. Fortunately, there is an HMI indicator/controller that addresses this issue — the 820i. The 820i programmable indicator/controller gives you immediate access to frequently used functions such as formula selection or batch start with soft programmable keys. Configure up to 100 setpoints to operate as free, sequential, or interlocked operation; In addition, customize setpoints with triggers defined by default weights or events and actions. The 820i can weigh in batches by gross weight, net weight, percentage of the target or by time. Accurate batch weighing and consistent quality are attained by using machine learning or preact flow functions. By presetting the soft keys, fixed messages can be automatically sent to a remote screen. With open connectivity to the most popular interfaces, the 820i system integration is impeccable. Reproducibility, tighter quality control, waste reduction, system integration, increased productivity and ease of use — that is the power of 820i.
