| description | The invention relates to a capacitive measuring tilt sensor (1), comprising a cavity (20) with a fluid (21) and a bubble (22). The cavity (20) is configured with, an electrically conducting or conductively plated dome (14) forming a dome electrode, and a base (24) with at least three, preferably four, bottom electrodes (12). A capacitance measuring unit (11) is configured to determine electrical capacitances (25) between the dome electrode and each of the bottom electrodes (12), and an evaluation unit (11) is configured to derive a tilt information on basis of the capacitances (25). The base (24) is therein configured as an electronic PCB (10) comprising conductive tracks (10t) and isolating base material (10i) and the bottom electrodes (12) are formed by the circuit tracks (10t) of the PCB (10) under the dome (14). According to the invention, the cavity (20) and the fluid (21) are configured in such a way, that the bubble (22) touches a top of the dome (14) the base (24) and the bottom electrodes (12) are covered by an additional layer (17) of material in-between the electrodes (12) and the fluid (21), which layer (17) is configured to provide a surface that is configured to be wetted by the fluid (21). |
