Abstract :
This paper discusses approaches for online moisture determination of wood pellets by means of capacitive sensing. Two different electrode topologies, one based on parallel plates and the other on a planar structure, are analysed and tested using a laboratory prototype in a drying chamber. In a further investigation, the susceptibility of the topologies on the orientation of tested wood pellets is examined.
