Symmetrical Dual Redundant (SDR)
The Symmetrical Dual Redundant (SDR) scale represents the highest level of assurance in conveyor weighing. Combining two fully suspended weigh frames operating in series, it continuously cross-checks performance to detect discrepancies and verify measurement integrity in real time.
Built for high-value, high-consequence operations such as shiploaders and trade certified load-out conveyors, the SDR provides unmatched confidence in every transaction. It’s the ultimate solution for operators who demand verified accuracy, accountability and complete peace of mind in mission-critical applications.
