Abstract
A sensor has a self-test function, a movable part and an evaluation unit. The movable part has its own drive. The measured variable is represented by a deflection of the movable part with respect to a reference position. Because of the drive, there is at least one additional, parasitic deflection of the movable part. The self-test function is implemented by the valuation of the parasitic deflection in the evaluation unit.
