Capacitive sensors are often known as the capacitance level meter, capacitance level meter capacitive sensing element is a cylindrical capacitor according to the principle of work, by the two capacitor plates insulated coaxial cylindrical inner and outer electrodes electrodes, between the two cylinders filled with a dielectric constant e of the electrolyte, the capacitance between two cylinders for the C = 2ΠeL/lnD/d, where L is the overlapping part of two tube length; D electrode diameter for the outer tube; d is the diameter of the inner cylinder electrode; e is the dielectric constant of the intermediate medium. In the actual measurement D, d, e is basically unchanged, so you can know the level measured at the level of C, which is easy to use with capacitive sensors, a simple structure and high sensitivity, low price and so one of the reasons .
