Abstract (en)

[origin: WO2007147950A1] A dewatering element (100) is connected by radio-frequency electromagnetic radiation from an object to be measured (102) to a measuring device unit (900) measuring water content and the dewatering element (100) acts at an interface between the measuring device unit (900) and the object to be measured (102) both structurally and operatively as a coupling element whose relative permittivity is higher than 75. The surface of the dewatering element (100) is partly metal-coated. The dewatering element (100) transfers radio-frequency electromagnetic radiation of less than 1 GHz between the object to be measured (102) and the measuring device unit (900) for measuring water content in the object to be measured (102).
