Устройство для контроля степени локальной коррозии металлических сооружений в проводящих средах, состоящее из электрически замкнутого на контролируемое сооружение полого корпуса, помещенного в ту же среду, изготовленного из того же металла, что и сооружение, отличающееся тем, что, с целью своевременного дистанционного обнаружения опасной степени локальной коррозии весь корпус или контактирующая со средой его часть, которой может служить и участок стенки сооружения, имеет меньшую, чем стенка сооружения, заранее установленную толщину, полость корпуса заполнена непроводящим инертным капиллярно-пористым материалом, в который введен металлический электрод, что при локальной коррозионной перфорации корпуса или его более тонкой части приводит к всасыванию среды внутрь и образованию между корпусом и электродом электрического контакта, который обнаруживается по электрическому сигналу, регистрируемому прибором, подключенным к выведенным наружу от корпуса (или сооружения) и электрода изолированным проводником.A device for monitoring the degree of local corrosion of metal structures in conductive media, consisting of a hollow body electrically closed to a controlled structure, placed in the same medium, made of the same metal as the structure, characterized in that, for the purpose of timely remote detection of a dangerous degree local corrosion, the entire housing or its part in contact with the medium, which can also serve as a section of the wall of the structure, is smaller than the wall of the structure, a predetermined thickness, the body cavity is filled with a non-conductive inert capillary-porous material into which a metal electrode is inserted, which, with local corrosion perforation of the body or its thinner part, leads to the absorption of the medium inward and the formation of an electrical contact between the body and the electrode, which is detected by the electrical signal detected by the device, connected to the insulated conductor brought out from the body (or structure) and the electrode.
