NON-INVASIVE MEASUREMENT OF DIELECTRIC PROPERTIES OF A SUBSTANCE

摘要

The invention pertains to an apparatus for determining the dielectric property of a first substance in a composition in a non-invasive manner, the composition comprising at least the first substance to be measured and a second substance, comprising a capacitor for creating a field into which the composition can be introduced at least in part, wherein the capacitor is part of an oscillator circuit, and a device for determining the resonance frequency of the oscillator circuit, wherein the capacitor comprises a layer of a non-conducting material such that the composition, when introduced at least in part into the field of the capacitor, does not come into an electric contact with the electrodes.
