Abstract:
A capacitive measuring sensor, comprising: at least two corresponding capacitor electrodes of flat design and having planar surfaces, set at an acute angle to one another, with their point of intersection constituting the center of rotation for a change in angle between the electrodes such that the following relationship holds: 1c=h0+Î”&it;â€ƒ&it;h&varepsilon;0&it;bl2&CenterDot;ln&it;â€ƒ&it;l2l1where I1, I2 are the starting and final points of the electrodes from the center of rotation upward, b is the width, &egr;0 is the dielectric constant, h0 is the initial opening and &Dgr;h is the change in distance, whereby a distance to be measured can be converted into a corresponding change in angle with a corresponding change in capacitance.
