Radar sensors
NivoRadar® - NR 8500 | Horn antenna high-temperature
Continuous level measurement
Liquids
The NivoRadar® 8500 provides continuous level measurement of liquids, even under extreme process conditions. This radar sensor is equipped with a robust stainless steel horn antenna and is the ideal solution for high-temperature and high-pressure applications. Thanks to high-quality materials and reliable seals, the NivoRadar® 8500 operates precisely at temperatures up to 450 °C and pressures up to 160 bar. The narrow beam angle of only 3° ensures highly accurate measurement results even over longer distances.
Time-saving and easy commissioning via the UWT LevelApp, the integrated display, or PACTware
Reliable and precise level measurement thanks to 80 GHz radar technology
Maintenance-free sensor, even under extreme process conditions
