    • A tilt sensor having a printed circuit board disposed in a direction normal to a reference plane for measuring a tilt angle with a pair of electrodes formed on a first surface of the printed circuit board. A cover is affixed to the printed circuit board and creates a cavity between the cover and the printed circuit board with a predetermined gap between the cover and the pair of electrodes, the cover acting as a common electrode to the pair of electrodes to create a pair of capacitors. An inert liquid is contained in the cavity, the surface level of the inert fluid varying according to the tilt angle of the reference plane. A signal processing circuit is formed on a second surface of the printed circuit board that produces an output signal corresponding to a difference in capacitance between the two capacitors as a tilt angle detection output.
    • 一种倾斜传感器,其具有布置在垂直于参考平面的方向上的印刷电路板,用于测量与印刷电路板的第一表面上形成的一对电极的倾斜角度。 盖子固定在印刷电路板上,并且在盖子和印刷电路板之间形成一个空腔,在盖子和一对电极之间具有预定的间隙,盖子用作一对电极的公共电极以形成一对 的电容器。 惰性液体包含在空腔中,惰性流体的表面水平根据参考平面的倾斜角度而变化。 信号处理电路形成在印刷电路板的第二表面上,其产生与两个电容器之间的电容差相对应的输出信号作为倾斜角度检测输出。
