Abstract

A sensor arrangement for non-invasive measurements of dielectric permittivity of liquids comprises a signal splitter, a reference path coupled to said signal splitter including a reference sensor comprises a reference fluid container containing a reference fluid, and a measurement path including a measurement sensor that receives the other one of said input signals and comprises a measurement area. A combiner adds a reference signal output on the reference path and a measurement signal output on the measurement path to obtain a sensor signal. A processor determines a change in amplitude and/or phase of said sensor signal compared to one or more reference signals obtained in reference measurements using reference fluids and determines the dielectric permittivity of the measurement fluid from said determined change in amplitude and/or phase of said sensor signal. The reference sensor and the measurement sensor each comprises two or more coupled microstrip lines.
