Abstract
An oil quality sensor to determine the quality of deep-frying oil by measuring the capacitance of the deep-frying oil in a deep fryer includes a housing and a hollow space in the housing through which the deep-frying oil is guided. An inlet opening introduces deep-frying oil to the hollow space, and a drain opening guides the deep-frying oil out of the hollow space. A first bent electrode extends along the hollow space, and a second bent electrode extends along the hollow space and is arranged opposite the first electrode, in which case the two electrodes form a capacitor and deep-frying oil is guided through the space formed between these two electrodes to measure its capacitance. A first temperature sensor measures the temperature of the oil used for deep frying that needs to be measured. An evaluation unit records the measured capacitance of the capacitor and the measured temperature, digitalizes these measured values, and calculates the polar fractions in the deep-frying oil, in which case these polar fractions are a criterion for the quality of the deep-frying oil.
