Capacitive measuring methods are used to measure the level of liquids through the container wall, to classify liquids and to measure pressure.
Capacitive sensing is based on a change of properties of a pair of electrodes (generalized plate capacitor) with variations in these electrodes’ environment. This can involve the use of geometric effects (e.g. in the case of capacitive distance measurement) or changes in material properties (e.g. in the case of fill level sensors). The analysis methods developed by AST for these effects maximize both precision and insensitivity to external interferences. Capacitive sensor systems have the advantage of offering extremely high resolutions. At AST, capacitive methods are predominantly used to measure the fill level of liquids, to measure the concentration of non-conductive liquids, and for measuring distance with extreme precision
