Radar Level Sensor: quick and precise up to 10m

Trouble-free level monitoring

The new radar level sensor LW2720 sets new benchmarks for speed and accuracy.
Starting with installation in record time: A standard M12 cable, fast parameter setting using IO-Link and a large selection of adapters enable simple and customized out of the box start-up. ​

If LW2720 is for example active in tanks up to 10 meter precise level measurement is still possible with integrated mixers or sprayballs. Also different media do not have a detrimental effect on measurements. Even the high-speed filling or emptying of tanks are registered by the radar sensor thanks to the 80GHz technology – fast, with high precision and without blind zones. ​

Applications

Use Case in a brewery

Fermentation tank

The radar level sensor is used for continuous level measurement in a fermentation tank. Tanks equipped with a jet cleaner and have a conical bottom pose a challenge for level measurement. Thanks to the LW’s operating frequency of 80 GHz it provides a narrow beam and is therefore not influenced by the jet cleaner. The narrow beam of the LW provides a reliable measurement of the conically shaped tank bottom without interference from stray reflections.

IO-Link benefits

  • Loss-free data transmission
    Digital transmission of the level value
  • Plug & Work
    Easy installation. Only one parameter is required.
  • Remote maintenance
    Remote parameter setting and level monitoring are possible using IT-connectivity

How does radar level measurement function?

Technology

The device works according to the FMCW method (FMCW = Frequency Modulated Continuous Wave). Electromagnetic pulses in the GHz range are sent to the medium at a constantly changing frequency between 77 and 81 GHz. Since the transmitter continuously changes the frequency of the transmitted signal, there is a frequency difference between the transmitted and the reflected signal. The frequency of the reflected signal is subtracted from the frequency of the signal transmitted at that time, resulting in a low frequency signal proportional to the distance to the level. This signal is further processed in order to obtain fast, reliable and highly accurate level measurements.
