CorrSen is a highly-sensitive wireless device for the real-time monitoring of atmospheric corrosivity. The device records electrical resistance of a thin metallic sensor (ER sensor) placed on a non-conductive substrate and exposed under corrosive conditions. As a result of corrosion process, sensor thickness decreases leading to the electrical resistance increase which is directly recalculated to the corrosion depth, actual corrosion rate and environmental corrosivity.
Owing to the simple operation principle, the device is easy maintainable and provides direct corrosion data in all types of atmospheres. Simultaneously with the corrosion rate, temperature and relative humidity are recorded by the logger to provide the overview of environmental factors effect on the environmental corrosivity.
