Abstract:
An apparatus for measuring corrosion in a gaseous environment containing chemically reactive gases or water vapor, said apparatus comprising:a sensor, in the form of a sandwich structure, the sensor comprising:a plurality of strips of a first conducting material (M.sub.1), alternated by a series of strips of a second conducting material (M.sub.2), wherein said strips of the first conducting material (M.sub.1) and said strips of the second conducting material (M.sub.2) are electrically connected and said materials are dissimilar: anda plurality of thin strips of a non-conducting material, wherein said strips of non-conducting material separate said series of strips of said first conducting material (M.sub.1) from said strips of said second conducting material (M.sub.2) to form said sandwich structure, wherein said strips of non-conductive material are sufficiently thin, having thicknesses of about 0.01 to about 0.05 mm, such that that they comprise means for reacting with humidity in said reactive gaseous environment to form thin films of absorbed, solution the thin films of adsorbed solution bridging the gaps between the plurality of strips of the first conducting material and the plurality of strips of the second conducting material.
