Electrical model of a capacitive based level sensor

The capacitance level measurement process involves first of all knowing the capacitance of the sensorial part of the built system. For the parallel plate capacitive sensor behavior modeling, it is mandatory to take into consideration the influence of the dielectric materials between the plates. Also, knowing the dielectric position in respect with the capacitor's plates, respectively the total parasitic capacitance, the electrical model of the multi-capacitive sensor can be revealed.
