Abstract: An atmospheric corrosion sensor for detecting corrosion of electrical equipment comprising at least two atmospheric corrosion sensing structures placed on at least one insulated corrosion sensor substrate wherein the corrosion sensing structures are accessible to corrosion atmosphere. The atmospheric corrosion sensing structures have the same spatial dimensions and each of said atmospheric corrosion sensing structures comprises a different composition of corrodible material.

Abstract: An atmospheric corrosion sensor for detecting corrosion of electrical equipment due to corrosive gas comprising at least one atmospheric corrosion sensing structure placed on at least one insulated corrosion sensor substrate, wherein the atmospheric corrosion sensor comprises at least one gas permeable layer placed on the corrosion sensing structure, wherein the gas permeable layer allows for transferring the molecules of corrosive gases present in the atmosphere to the surface of the sensing structure, opposite to the insulated corrosion sensor substrate, causing it to corrode.
