Zusammenfassung:The invention relates to a micro-electro-mechanical acceleration sensor system. The invention relates to a sensor system having a micro-electromechanical acceleration sensor element for detecting acceleration values acting on the acceleration sensor element, a Sigma-Delta analog-to-digital converter for converting an analog output signal of the acceleration sensor element into a digital output signal of the sensor system, and a first signal generator element and a second signal generator element, a first signal generator element is connected between the acceleration sensor element and the analog-to-digital converter and is configured to apply an output signal of the acceleration sensor element with a predetermined signal value, the signal value of the first signal generator element corresponding to an acceleration value greater than the average gravitational acceleration, the second signal generator element is connected downstream of the analog-to-digital converter in the signal processing direction and is co
