system for monitoring the stray current in the tunnels and viaducts in reinforced concrete

摘要

a provision circuitale is described which allows the monitoring of current source is scattered stray currents in the tunnels and viaducts) in reinforced concrete and evaluationconditions for the onset of corrosion phenomena or embrittlement of hydrogen on steels with high mechanical properties.the found is composed by a system of sensors for measuring the potential of the armor and the circulating current in the concrete and several logical units to carrying out monitoring.and automated system and carry out the processing of information received from the sensors to signal the occurrence of hazardous conditions.
