Applications
The Span LR300 series is used in industrial and process weighing systems where multiple scale inputs must be monitored and controlled from a single terminal. Typical deployments include manufacturing floor weigh stations, batching and filling lines, hopper and tank weighing, and any application requiring simultaneous display and alarming across two independent load cell channels. The RS-232/RS-422 serial interface allows the terminal to be integrated with PLCs, data acquisition systems, or host computers for data logging and process control. These terminals are also found in quality control labs and distribution environments where accurate multi-channel weight data is critical.
