NivoGuide^® - NG 8100

Continuous level measurement, Interface level measurement
Liquids
DK value ≥ 1,4

Application area

The guided radar sensor NivoGuide^® 8100 measures the level of liquids or oils of any kind. In addition to level measurement, this TDR sensor can also reliably and precisely detect an interface, which is likely to be formed between two liquids. Due to the robust sensor design and a wide range of versions, the sensors are suitable to be used in large storage tanks as well as in small process vessels or bypass tubes.

Your benefit

Simple, menu-driven commissioning and diagnostics with operating module and display
High measurement reliability even in applications with steam, foam formation or condensate to reduce unwanted downtimes
Maintenance-free sensor
SIL 2/3 certified
