Personalize Your Process

To gain the competitive edge 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. Meet the Rice Lake 820i.

The 820i revolutionizes basic instrumentation programming, allowing for more affordable serviceability and programming support. Unlike many programmable indicators, the 820i features an intuitive user interface that enables users to automate formula selection, batch start up, data recall, or any frequently used process with the push of a button. With the 820i on board, increasing accuracy and improving the efficiency of any weight-related process has never been easier.

With open connectivity to the most popular networking interfaces, 820i system integration is seamless. Repeatability, tighter quality control, waste reduction, system integration, increased productivity and ease of use — that’s the power of the 820i.

In any batching application, it’s a challenge to provide accurate, quality products while attempting to reduce costs. Fortunately, there’s an HMI indicator/controller that will keep your process on target—the 820i. The 820i gives you instant access to frequently used functions such as selecting a formula or starting a batch with programmable soft keys. Configure up to 100 setpoints to operate as freerunning, sequenced or latched; and customize setpoints with weight-based or event and action defined triggers. The 820i can batch in gross weight, net weight, percent of target or by time. Precise batching and consistent quality are attained by using automatic learning or flow preact.By presetting soft keys, fixed messages can be automatically sent to a remote display.
