  • Patent number: 11662265
    Abstract: A compensating of the sensor module occurs with the implementing of the transfer function in the measuring circuit of the sensor module. The transfer function generates sensor measured values as a function of primary signal. In a later sensor calibration, sensor measured values provided on the sensor module interface are registered as a function of supplied pressure values and stored in a calibration database. In a later electronics module calibration, measured value signals provided on the signaling interface are registered as a function of sensor measured values supplied by means of a calibration signal source and stored in a calibration database, wherein the supplied sensor measured values correspond to the sensor measured values of the sensor calibration. Finally, there follows the calibration protocol creation, in which the measured value signals ascertained in the electronics module calibration are associated with the pressure values supplied in the sensor calibration.
