Radar sensors

NivoRadar® - NR 3100

Application area

The free-radiating radar sensor NivoRadar® 3100 is mainly used in storage silos for level measurement of bulk solids. The 4 ° narrow beam and a measuring range of up to 100 meters make the sensor a compatible solution for a wide range of applications in the field of non-contact measuring technology. The easy to operate display, the Quick Start Wizard and displayed diagnostic data allow simple installation on site.
