Radar sensors

NivoRadar ® - NR 7200

Application area

The non-contact 80 GHz FMCW radar sensor NivoRadar® NR 7200 with a narrow beam angle of 8° is used in various industrial applications in storage silos, process tanks, IBC containers or open basins for continuous level measurement. The free-radiating level transmitter has a compact design with a 1 1/2″ process connection (PVDF) and a measuring range of up to 15 m as well as a very fast response time. The radar sensors are food compliant, WHG-certified and suitable for use in hazardous areas. The radar level transmitters can be used in aggressive media such as acids, alkalis and solvents as well as in highly viscous liquids and oils.
