Point level detection with microwave barriers 

The microwave barrier functions like a light barrier: when the medium gets in the way of the microwave beam between the transmitter and the receiver, the signal is attenuated. This signal attenuation is detected by the receiver and converted into a switching signal.
In addition, microwaves are able to penetrate non-conductive materials. This means: with containers made of plastic or glass it is possible to measure right through the container walls.
Another useful application is object monitoring, e.g. detecting the position of trucks that are being loaded, or preventing crane collisions.

The advantages

Point level detection with microwave barriers operates contactlessly and is not affected by soiling both in solids and in liquids. This ensures wear and maintenance free operation.
