Measuring instrument and method for determining the alcohol content of a mixture

摘要: A measuring instrument has a configuration and circuit. The circuit determines the capacitance of capacitor conductance configuration, which is formed casing sensor element around mixture flows. alcohol content determined therefrom. an oscillator control connected upstream thereof. represented by conductance, part oscillator, oscillates within cycle at three different frequencies are set voltages circuit, evaluated in microcontroller. Component tolerances influence can thus be taken into account.
