Abstract:
An accelerometer for detecting inertia forces, comprising:a vessel having several separable and immiscible media held therein, wherein at most one medium is gaseous and the other media are liquid, and the media are arranged one above the other by gravity;at least phase boundaries formed between the media;a detector which detects a positional change of the phase boundaries in the case of an appearance of acceleration;an evaluator which evaluates a dynamic positional change for gradual determination of the acceleration;wherein the detector detects the positional change of the phase boundaries, which are formed by at least three separable and immiscible media, as a detection signal, at least two of the media being liquid;wherein the detector determines the detection signal as an acceleration signal and feeds the acceleration signal to the evaluator; andwherein the media form between the phase boundaries independent of one another as discrimination means for discriminating the dynamic positional change from a static positional change.
