2.2.1 Sensors
For this measurement system, several sensors can be used. In order to obtain accurate
measuring results, the surface of the sensor must be kept clean and free from damage.
The capacitive measuring process is area-related. A minimum area (see table) is re-
quired depending on the sensor model and measuring range. In the case of insulators
the dielectric constant and the target thickness also play an important role.
