The non-contact radar sensor with a very narrow beam angle of (4 to 8) degrees is used in various industrial applications in storage silos, process tanks and IBC containers or on stockpiles for continuous level measurement. The free-radiating level transmitter has a measuring range of up to 100 m as well as a very fast response time. The radar sensors are food-compliant, WHG-certified, and suitable for use in hazardous areas. The radar level transmitters have a high dust protection class and can be used in abrasive bulk materials as well as materials prone to caking.
