ABSTRACT:
The acceleration sensor has an elastic member (11) to which an inertial body (12) is attached. Upon the occurrence of an acceleration force, the elastic member (11) is deformed. In order to measure the absolute value of the acceleration, a calibration may be performed. In such calibration, a measuring value of the acceleration is obtained from the excursion of the inertial body (12) at a given density of the medium surrounding the inertial body. Subsequently, a second measuring of the same acceleration is taken at a varied density of the gas surrounding the inertial body, thereby obtaining a second measuring value. In further measurements, the absolute value of the acceleration may be calculated from the differences between the gas densities and the measured values.
