FIELD: instrumentation.
SUBSTANCE: proposed device consists of corroding metal plates of different thickness smaller than that of metal structure wall made of the same material as said metal structure. Note here that one side of every plate faces the corroding medium. Opposite side of the plate is jointed electrically and mechanically to protector of the same sizes as said plate and made of metal with more negative potential of corrosion in said corroding medium than metal plate. Every plate and every protector make transducers electrically isolated one from another while protector is isolated from said medium by antirust dielectric coating. Note here that every transducer is fitted in case made of antirust dielectric material. Said every transducer stays in electric contact with metal structure via set of switches and ammeter.
EFFECT: reliable remote diagnostics irrespective of pressure, temperature, medium transfer and structure type.
