Radar Sensors for Level Measurement

Radar sensor for continuous and contactless level measurement in liquids, pastes, sludges and bulk solids

For Challenging Applications

  • Latest FMCW radar technology with 63 GHz
  • Insensitive to gas, pressure, mists or temperature fluctuations
  • Compatible with all NivuMaster versions
  • Measures through plastic containers
  • Compact and easy to install
  • Robust and flood-proof IP68 housing
  • ATEX Approval for Zone 0/1 

 

The new R-Sensor is a radar sensor for continuous and contactless level measurement in liquids, pastes, sludges and bulk solids. 

Measurements are not affected by changing media, temperature fluctuations, gas ­overlays or vapours. The radar sensor utilises the latest 63 GHz FMCW technology which, compared to   pulsed radar methods, has several advantages:

  •  Improved spatial allocation 
  •  Larger dynamic range
  •  More reliable surface detection   

Therefore, it is very easy to retrofit existing equipment setups after updating the firmware.

R-Series sensors provide accurate measurement values in closed tanks or outdoor applications (e. g. dams, rivers etc.). 

A very low dead zone and the narrow 
beam angle allow for reliable measurements even in confined spaces.
