More Information
Summary:An inclination sensor for measuring angles and flatness over a wide range of ambient temperatures, and suitable for use in crane apparatus and conveying plant, in building construction and as an electronic spirit level, comprises a differential capacitor with a coupled evaluation device. The differential capacitor is disposed in a closed chamber 1, 2 and is formed from a pair of identical capacitor plates 3, an electrically conductive fluid 5 conductor 6 as a counter-electrode and a dielectric of a solid insulating layer 4, e.g. glass, applied to the plates 3. When the device is level the plates 3 are disposed symmetrically about a vertical axis and are shaped to have a horizontal axis if symmetry coincided with the level of fluid 5. According to the coverage of the surfaces of the capacitor plates by the fluid, the capacitance measured at the capacitor plates alters in opposite directions when the sensor is inclined, and a proportional angular change is determined therefrom.
