Radar sensors

NivoGuide® – NG 3100

Application area

The guided radar sensor NivoGuide® NG 3100 is used for continuous level measurement in bulk solids applications from a Dk value of 1.5. The large measuring range up to a vessel height of 75 m covers many applications in bulk solids. Intuitive operation and a Quick Start Wizard makes commissioning simple and safe.
