CORROSION DETECTOR Russian patent published in 2010 - IPC G01N17/04 

FIELD: physics.

SUBSTANCE: corrosion detector comprises assembled magnetic conductor, consisting of steel pipe 1 section and core in the form of composite coil placed inside. Steel half-coils 2 are connected by coupling 3 from non-magnetic material, at the same time windings 4 are wound on steel half-coils 2. Cavity of detector contains contact electrode 5, which is arranged with cylindrical, moisture absorbing material 6, epoxide compound 7, connection wires 8. At the same time section of steel pipe 1 is sensitive element and body, slit cavity between body and contact electrode 5 is filled with moisture absorbing material 6. Epoxide compound 7 serves for insulation of external surface of half-coils 2 from soil, and connection wires 8 are brought to surface of earth into control and measurement.

EFFECT: improved accuracy of control and assessment of electrochemical protection facilities operation efficiency and prediction of nature and speed of corrosion damages.
