Monitoring Of Bridges Corrosion Level

Abstract

Corrosive damage level of bridge constructions becomes high discussed topic with regard to some recent incidents. Current system of inspections is based mostly only on visual inspections in the Czech Republic. Our solution proposes to build-in a humidity sensor inside a bridge structure to detect leaking water and damage level during long period. Text focuses on description of basic principles of humidity measurement and performed experiments with sensors implemented in porous material showing possibility of measurement inside a structure. Finally, a market research of commercially available sensors is documented with narrowing selection suitable for this application.
