Sensors for Metal Corrosion Monitoring

Abstract

A novel sensor used for metal corrosion monitoring comprises a power supply module, an MCU control module and a corrosion monitoring module; the power supply module is used for powering up the MCU control module and the corrosion monitoring module; the MCU control module is used for controlling the corrosion monitoring module and analyzing and processing information from the corrosion monitoring module; and the corrosion monitoring module is used for monitoring the corrosion condition of metal to be detected, and uploading data to the MCU control module in real time. The novel sensor adopting noncontact measurement completes short-term pre-estimation and long-term monitoring of the metal corrosion degree. A result of test shows that the performances of the sensor are comparable to those of a desk type constant potential instrument with high price and large size, and so the monitoring ability of the corrosion degree of the metal and especially a steel material is improved.

Description

technical field [0001] The invention relates to the field of metal corrosion monitoring, in particular to a sensor for metal corrosion monitoring. Background technique [0002] Reinforced concrete structure is one of the main structural forms that will be used for a long time now and in the future, and the corrosion of steel bars is the main reason for the reduction of durability of steel-concrete structures. According to the survey by the National Materials Advisory Committee of the United States, nearly 253,000 concrete bridge decks have serious corrosion; about 21.4% of the reinforced concrete structure damage in Japan is caused by steel corrosion; at the end of 2002 in my country, there were 9,597 dangerous highway bridges alone, and the cost A 40 million yuan bus station in Shandong became a dangerous building in 2009, five years after it was completed. The main culprit was the corrosion of steel bars. Therefore, the monitoring of metal corrosion is imperative. [0003...
