The SICK LFR SicWave Series Level Sensor integrates a free-space radar for continuous level measurements, and works with all liquids. These products are highly resistant to external interference, foam or deposits. Thanks to its non-contact 80GHz radar technology, the LFR SicWave can be put into operation easily and is maintenance-free. A wide range of options for antenna design, process connections and housing ensure ideal connection to any application. HART communication and WPAN connection simplify service and diagnostics on the device and prepare it optimally for Industry 4.0 applications.
