Calibration of a capactive position sensor
Author: Jaroslav Švoma
The aim of this bachelor work was to propose and to realize a procedure for calibration of a capacitive position sensor. The sensor is a differential capacitive position sensor with variable overlapping of electrodes. The calibration procedure had to be proposed with regard to parasitic phenomena, which influence the sensor characteristic. At first, the parasitic phenomena were characterized. In the next step, a simple experiment to separate these parasitic phenomena from the intended position measurement was proposed. This experiment was used as a basis for design of the calibration procedure.
