Cardinal SmartCan Digital Conversion System

You can now digitize any existing analog scale using Cardinal Scale’s SmartCan analog-to-digital conversion system. SmartCan allows users to digitally monitor each individual load cell and identify cell failures quickly and effectively. The SmartCan system utilizes the advanced, internationally-standardized CAN (Controller Area Network) serial bus system to digitize the analog output signals from two or more independent load cells and send the data to the indicator. SmartCan may be used in a variety of different applications with new and existing truck scales, railroad scales, floor scales, bench scales, and batching systems. SmartCan is housed in a compact, rugged weatherproof IP66 / NEMA 4 enclosure and doesn’t require cumbersome external power supplies, in most applications.
