July 1, 2006

Rice Lake, WI, June, 2006 — Rice Lake Weighing Systems, a leader in the weight-based measurement and process control industries announces the release of the 820i programmable HMI indicator/controller.

The 820i revolutionizes basic instrumentation programming, allowing for more affordable serviceability and programming support. Featuring an intuitive interface, the 820i allows users to automate formula selection, batch start up, data recall, or any frequently used process with the push of a button.

Rice Lake’s iRite IDE (intuitive development environment) PC-based software is standard on the 820i. Using graphical flow charts, this unique software does away with complicated code generation. Users simply link command-specific graphics to design or modify a process.

Built-in software functionality includes programmability for alibi tracking, 25 definable print formats, and multi-range (interval). The 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.

With the 820i, increasing accuracy and improving the efficiency of any weight-related process has never been easier.
