  • Patent number: 11041777
    Abstract: A method for checking the plausibility of a pressure sensor that, during the measurement of a differential pressure, records measured values, whereby the measured values from the pressure sensor are compared to reference values for the differential pressure calculated on the basis of a model; whereby in order to determine the plausibility, at least one deviation of the measured values from the reference values and a difference between a first slope of the changing measured values and a second slope of the changing reference values over the curve of the measured values are taken into account.
