摘要
1. Circuit for indicating and eliminating the danger of corrosion, for metal structures in underground channels, which are periodically flooded with water, consisting of a standard measuring electrode and controlling amplifier, characterized in that the measuring electrode (1) is connected on one side, via a unit consisting of a resistor and a diode (2), whose direction of conductance depends on the electrochemical properties of the electrode, to the protected structure (3), and on the other side to the amplifier (4) controlling a relay circuit (5), which activates the signal of a remote signalling system (6).IMAGE
