<p>Cylindrical capacitance force sensing device/method is disclosed. In one embodiment, an apparatus includes a capacitor having two parallel conductive surfaces, a cylindrical housing with a cover plate to encompass the capacitor, and a sensor in the cylindrical housing to generate a measurement based on a change in a distance between the two conductive surfaces when the cover plate is deflected by a load applied on the cover plate. In another embodiment, a method may include applying a load on top of a housing which encompasses a capacitive sensor having two parallel conductive surfaces to produce a deflection of a cover plate of the housing, automatically generating a measurement from the capacitive sensor when a distance between the two parallel conductive surfaces is changed due to the deflection of the cover plate, and decreasing an error in the measurement via stabilizing the housing to a mounting surface.</p> |
