Radar sensors

NivoGuide® – NG 8200

Application area

The guided radar sensor NivoGuide® 8200 measures the level of liquids or oils under most extreme process conditions. The extremely robust sensor construction, resistant materials as well as a special reference line extend the field of application of the TDR sensors by high-pressure, high-temperature and saturated steam applications. Thus, temperature ranges from -196 °C … 450 °C and process pressures up to 400 bar can be covered.
