Abstract (en)

[origin: WO2022029244A1] Empirically, a sensor arrangement for determining a quality and/or a degree of contamination of a liquid, in particular in a container, is provided. The sensor arrangement has at least one conductance sensor which is configured to determine a conductance of the liquid, and at least one capacitance sensor which is configured to determine a capacitance of two measuring bodies in the liquid. The sensor arrangement also has at least one computing unit. The latter is configured to determine the quality and/or the degree of contamination of the liquid taking into account the measured values of the conductance sensor and the capacitance sensor. A method for determining the quality of the liquid using the sensor arrangement is also provided.
