Abstract
A sensor measures a sample in a measuring cell including a helix conductor. The shell structure of the measuring cell is made of an electrically non-conductive material. The measuring cell and at least part of the helix conductor are placeable inside a chamber. A radio-frequency signal input element couples a radio-frequency signal to the chamber to form a helix resonance. A radio-frequency signal output element is responsive to a helix resonance of the helix conductor and transmits a radio-frequency signal for measurement. A device for measuring a sample in a measuring cell includes the sensor, a radio-frequency signal source, and a measuring and control part. The radio-frequency signal source produces a radio-frequency signal to the input element. The measuring and control part measures a property of a sample on the basis of a resonance frequency.
