Acceleration pick-up device
First Claim
1. An acceleration pick-up device having a body which is fastened to an elastic member, and a sensor for detecting the position of said inert body, characterized in that, for calibrating an absolute value of acceleration, the mass of the inert body is controllably changed by the addition or the receiving of a foreign medium, wherein the inert body, together with the elastic member and the sensor, is accommodated in a pressure-tight housing and wherein the foreign medium is introduced into said housing.

Abstract
The acceleration pick-up device is provided with an elastic member to which an inert body is attached. Upon occurrence of an accelerative force, the elastic member is deformed. For measuring the absolute value of the acceleration, a calibration can be performed. In this calibration process, a measuring value of the acceleration is obtained on the basis of the deflection of the inert body. Subsequently, the inert body is loaded with a foreign medium so that its mass is changed, and then a further measuring value is obtained. In further measurement processes, the absolute acceleration value can be calculated from the differences of the masses and the measuring values.
