Abstract
A sensing device includes a pair of contactless electrodes for placement on a coating on a surface of a structure or within or between one or more coatings on or over the surface of the structure. The electrodes function as sensors when activated to generate a current flow through the electrodes at multiple different frequencies. The sensing device also includes contactless control circuitry co-located with or separate from the electrodes that transmits impedance data generated from the activated electrodes. The impedance data is associated with corrosion condition information of the structure and/or the one or more coatings. A data collection system and display system useable with the sensing device are also described.
