Corrosion rate measurement can reveal which areas of a structure need immediate maintenance
and which ones will need maintenance later, as well as allow an optimal maintenance schedule to be
developed. A new stamp-sized corrosion sensor allows measurement of corrosion rates based on wellestablished
LPR (Linear Polarization Resistor) technology, which outputs an exact corrosion rate for
the structure on which it is placed. The corrosion rate data can be monitored continuously or stored in a
data collection node, to which 8 sensors are attached, and downloaded periodically. This sensor
technology is being evaluated in the laboratory under various simulated corrosive field conditions. The
sensor is being considered for corrosion monitoring applications on structures for mission critical
equipment on military installations in severely corrosive environments. Results of laboratory
experiments on the sensitivity of the sensor to the onset of corrosion on the substrate and projections
for its applicability in the field will be discussed.
