Measuring principle - The measuring system consists of a microwave emitter and a respective receiver. An emitting signal with a frequency of 24 GHz is focussed by an antenna system and emitted against the receiver. A medium in the path of rays damps this signal. This signal damping is detected by the receiver and converted into a switching signal. The adaption to the local conditions and the medium is easily possible by adjusting the sensitivity. Because microwaves can penetrate non-conductive products, a measurement through plastic vessels is possible. With metal vessels, mounting is carried out directly on the vessel or through suitable window materials such as for example plastic, glass or ceramic.

Applications in liquids - Microwave barriers are particularly suitable for measurement in plastic or glass vessels because no opening is required for mounting. The measurement can be carried out directly through the vessel wall.

Applications in bulk solids - The main application area of the microwave barrier is the level detection of bulk solids. The non-contact measuring principle is particularly suitable for harsh application conditions in mineral ore mining, coal or ore dressing.

Applications for object monitoring - Similar to a light barrier, the microwave barrier can be also used for object monitoring. Since microwaves are not influenced by dust, rain or fog and react virtually unaffected to soiling, they are the ideal solution for harsh operating conditions. Typical applications are loading of trucks in the quarry or collision protection. Due to the sensitivity of the receiver, an effective radius of more than 100 m can be reached.
