Method of changing a signal processing in a sensor system, comprising the following features: a) a measurement variable is detected, and a sensor signal (U) representing the measurement variable is generated, in a sensor element which is a component of a sensor unit, b) the sensor signal (U) is processed in a sensor signal processing unit, which is similarly a component of the sensor unit, according to predetermined parameters (C 1, C 2, C 3,..., C m,... C M), wherein the parameters (C 1, C 2, C 3,..., C m,.... C M) are set externally, c) at least one signal (Out) processed in the sensor signal processing unit is transmitted to an evaluating unit and evaluated therein, d) the evaluating unit newly determines on the basils of the transmitted signal at least one of the parameters for signal processing, e) the evaluating unit checks the validity of the at least one parameter and determines whether a change of the at least one parameter is required, f) the evaluating unit transmits in the case of a required change this at least one parameter (C 1, C 2, C 3,..., C m,... C M) via a connecting line present between the sensor unit and the evaluating unit, g) the sensor signal processing unit sets this at least one transmitted parameter (C 1, C 2, C 3,.... C m,... C M) and h) in the case of a required change of the at least one parameter (C 1, C 2, C 3,... C m,.... C M) this is transmitted in ongoing operation to the sensor signal processing unit (10, 25) only if the transmission of signals (Out) from the sensor signal processing unit is not disrupted by that, so that a constant updating of the parameter set in the sensor signal processing unit is ensured and the sensor system can operate in continuous operation. a) a measurement variable is detected, and a sensor signal (U) representing the measurement variable is generated, in a sensor element which is a component of a sensor unit, b) the sensor signal (U) is processed in a sensor signal processing unit, which is similarly a component of the sensor unit, according to predetermined parameters (C 1, C 2, C 3,..., C m,...
