Identify Problems Before They Happen

Rice Lake Weighing Systems’ iQUBE2® digital diagnostic junction box compares the output of each load cell to adjacent load cells, ensuring optimal performance and warning operators of weight irregularities. iQUBE2 converts any analog load cell system into a modern digital system, without replacing individual load cells.

Enhance the Performance of Any Scale System

iQUBE2 is ideal for systems using single or multiple scales with two or more load cells. Floor scales, hopper scales, tank scales, vehicle scales and dosing systems can all benefit from an upgrade to the iQUBE2 digital diagnostic junction box system.

With accelerated data transfer, batching and dosing applications can efficiently achieve target weights when speed and accuracy are critical.

Instant Alerts and Cell Emulation

Diagnostics can be viewed on the user interface and an email alert is sent in the event of a component error. If a load cell fails, the cell emulation feature calculates weight based on known comparisons to functional load cells, keeping your scale functional until the load cell can be replaced.
