NIVUS - Model R-Series - NMR - Radar Sensors for Level Measurement
From Level Measurement - Non-Contact Level Measurement - Level Sensors
The range of our non-contact radar and ultrasonic level measurement systems comprises radar and ultrasonic sensors and meters. The ultrasonic sensors range from the i-Series sensors, the NivuCompact echo sounder to the P-Series sensors and the OCL air-ultrasonic sensor. The R-Series operates with radar technology.
Description
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
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.
