    In such cases, we recommend repeating the false signal suppression at a later date with existing buildup. Mounting should not be too close to the inflowing material as the Inflowing medium microwave signal will be interferred. The optimum mounting position is on the opposite of the filling. To avoid strong pollution, the distance to the filter or dust extraction must be as big as possible. VEGAPULS 68 • Foundation Fieldbus...
