THE INFLUENCE OF THE NEAR-ELECTRODE IMPEDANCE OF THE CAPACITIVE SENSOR ON THE RESULT OF MEASURING THE ACTIVE AND REACTIVE COMPONENTS OF THE IMMITANCE

Influence of near-electrode impedance of capacitive sensor on result of measuring the active and reactive components of the admittance of electrolytic objects is considered. Near-electrode impedance is formed by capacity of the double layer and the Warburg impedance. Reactive and active components of admittance are the informative parameters of object’s electro physical parameters, in particular dielectric permittivity and specific conductivity.
