Definitions
- the known device described has the disadvantage that its construction is mechanically intricate because of the use of a gyroscope.
- the device is characterized in that the capacitors comprise a common first electrode plate and individual second electrode plates which are arranged symmetrically around the center of the space. Reading and processing of the measured capacitance values of the capacitors of such a device are simple.
- the space is filled with a liquid.
- the liquid damps movements of the body so that a quieter signal is obtained under circumstances with, for example, many vibrations.
- a liquid reduces the adhesion of the body to walls of the space, so that the risk of errors owing to, for example, stick-slip effects is reduced.
- the body of dielectric material and the space may be shaped so as to obtain a desired sensitivity for certain positions.
- the space has a rectangular box shape and the body has a cylindrical shape. The risk of the body getting stuck in corners of the space is very small then.
- the capacitors may be provided in the device in the form of a separate measuring unit (sensor).
- the device comprises a substrate on which both the capacitors and an electronic circuit for reading out or processing electrical signals obtained through the capacitors are provided.
- a substrate is present in that case, for example a printed circuit board or a silicon wafer, on which electronic units are provided for processing or reading of electrical signals which are influenced by the capacitance values of the capacitors, i.e. the position of the device, or the orientation of the body in the space.
