Flexible up to the probe tip: LFP Cubic level sensor

The LFP Cubic TDR level sensor works according to the principle of guided radar and is used, among other things, in containers of water treatment and purification plants or in tanks for hydraulic oil. Featuring an analog signal and now four switching outputs, the LFP Cubic level sensor provides extended possibilities for continuous level measurement and point level detection of fluids from 200 up to 2000 millimeters.

What makes the level sensor popular is its versatility. It is possible to shorten the measuring probe flexibly and to align the rotatable housing in the best possible way in every installation setting. The sensor is suited for a large number of fluids – even foaming ones – and requires no calibration either prior to commissioning or during ongoing operation, e.g., when changing the medium. Even build-up of deposits does not impair the accurate measurement of the LFP Cubic. In addition, new setting functions allow optimum adjustment of the sensor to the application.

Output signals for analog and digital measuring values

The LFP Cubic provides an analog output for continuous level measurement as well as IO-Link for individual parameterization, diagnosis, and visualization option as standard features on board. Using a doubled number of four switching outputs, the level sensor opens up new possibilities of combined detection and output of minimum and maximum point levels as well as relevant intermediate levels.


Coaxial tube extends range of use

With the optional coaxial tube, the LFP Cubic can be used in even more versatile ways, e.g. for level measurement in plastic tanks or close to agitators. Outside of containers, too, possible uses emerge, for example, for level and point level detection in pump sumps.
