Radar level sensor: Precise monitoring in industrial environments
Trouble-free level monitoring
The LW2120 radar level sensor measures levels of liquids and viscous media in tanks with a height of up to 10 metres precisely and without blind areas. The 80 GHz frequency that is used ensures stable and precise measurement results even in the presence of steam or condensate in the tank.
With the antenna extension, available as an accessory, the sensor may also be used outside closed metal tanks, for example on open tubs. The radar measuring system can penetrate through non-metallic walls, i.e. the level sensor can even detect levels in plastic tanks from outside.
What are the advantages of the radar level sensor?
The 80 GHz technology enables focused and precise level measurement even in demanding applications involving condensation, wind, steam, sunlight, or temperature fluctuations.
The non-contact measuring principle prevents malfunctions caused by the adhesion of media or damage from agitators.Even process conditions such as density, viscosity, temperature, pressure and pH do not impact the measurement.
Interfering structures are suppressed by the intelligent algorithm, minimising parameter setting and ensuring reliable and trouble-free level measurement.
Standard M12 connection technology reduces errors during set-up. Only one value is required for parameter setting, which makes set-up quick and easy.
With the antenna extension, available as an accessory, the sensor can also be used outside closed plastic tanks and above open tanks.
Use case - water treatment
Non-contact radar measurement in tanks
For more than 30 years, EnviroFALK GmbH has been designing, manufacturing and selling pure and ultra-pure water systems for a wide range of industries worldwide.For non-contact level monitoring in tanks, EnviroFALK uses the LW2120 radar level sensor.
The sensor can detect levels up to a height of 10 metres without blind zones and at a millimetre resolution. The 80 GHz frequency that is used ensures stable and precise measurement results even in confined spaces. With the antenna extension, available as an accessory, the sensor can also be used outside closed metal tanks, for example on open tubs or plastic tanks.
Standard M12 connection technology ensures error-free installation within minutes, while IO-Link adds the convenience of remote parameter setting and reading. The intelligent algorithm in the unit makes parameter setting via IO-Link seem like child’s play: After setting the reference height once, the sensor immediately provides the exact level via IO-Link.
Added value thanks to IO-Link
- Remote maintenance
Remote maintenance and parameter setting via established fieldbus systems and IO-Link
- No superstructures necessary
- Cost savings and increased safety
- Plug & work
The radar sensor can be configured quickly and easily via IO-Link. Only one parameter is required.
- Loss-free data transmission
IO-Link enables loss-free data transmission, as conversion losses are excluded via digital communication and external influences, such as magnetic fields, have no effect on data transmission.
