Abstract
A sensor arrangement for determination of at least one of a position and an acceleration of a moveable body has a housing fixedly connected with the moveable body, an inertia body accommodated in the housing, a detector arranged in the housing for detecting a horizontal displacement of the inertia body, the housing having a base plate on which the detector is arranged so that determination of a vertical displacement of the inertia body is also performed.
