Abstract (en)
[origin: WO2007017383A1] The invention relates to a method and device for operating a state sensor for liquids. In order to provide a method and device of the aforementioned type that has the ability to compensate for sensor-related zero-point and amplification changes, the invention provides that the sensor element S is, for electrical control with an input oscillation A of at least two different amplitudes and for receiving and evaluating measurement signals E, is connected to a controller C that is connected to a non-volatile data memory D, in which the values of the at least two different amplitudes of the exciting input oscillation A are strored.
