Abstract

The invention relates to a process and device for the continuous detection of the water content of bulk material, especially foodstuff or fodder components, with a microwave sensor. It is proposed here that the sensor be part of a measuring channel, especially as a triplate line. The conductivity of the sensor filled with bulk material is measured and the dampness calculated therefrom. The invention also relates to a measuring device in which the measuring channel has a back-pressure component for the bulk material on the output side and a rod transversely to the direction of product flow in the back-pressure region as part of the sensor. The measuring device takes the form of scales, preferably a beam scale.
