    • The invention relates to a sensor device for measuring attitude, acceleration or gravitational field and its gradient components. The device includes a spherical cavity (3) which contains a sensor substance in the form of a fluid or some other inertial material having fluidic properties. The cavity (3) is provided with measuring sensors or measuring electrodes (−x, +x; −y, +y; −z, +z) for three different coordinate axes x, y, z, all of said sensors responding to said common inertial mass which fills the cavity (3). Such assembled single compact measuring device can be used for determining any of the said quantities 3-dimensionally.
    • 本发明涉及用于测量姿态,加速度或重力场及其梯度分量的传感器装置。 该装置包括球形空腔(3),其包含流体形式的传感器物质或具有流体性质的一些其它惯性材料。 空腔(3)为三个不同的坐标轴x,y,z设置有测量传感器或测量电极(-x,+ x; -y,+ y; -z,+ z),所有这些传感器响应于所述 共同的惯性质量填充空腔(3)。 这种组装的单个紧凑测量装置可用于三维地确定所述量的任何一个。
