Abstract
Localized measurement system for monitoring corrosion inside a pole, adapted to verify the progress of erosion caused by the most common atmospheric agents on new metal poles used in telecommunications or lighting systems; such corrosion effects thus being capable of being monitored through the use of a diode whose construction parameters are known, inserted in a circuit whose sensitivity can be managed via a resistor R1, on the negative lead of an operational amplifier; each measurement being managed by at least a microcontroller, adapted to acquire the exploration cunent I, the temperature values in the environment around the diode, the n cyclic measurements, which are subsequently adapted to be sent to a remote control center; said measurement system being adapted to be incorporated inside a generic metal pole during its manufacture.
