CRANE-85003
Current methods used for detecting or measuring corrosion are non-quantitative and non-redictive. The "Non-Invasive Corrosion Sensor" will permit quantitative, continuous measurement of material surfaces not accessible during normal operations.

Naval Surface Warfare Center, Crane Division (NSWC Crane) has developed, tested, and patented technology for a non-invasive corrosion sensor. This innovative technology works based on the peltier effect, the principle that a temperature change is created by passing a current through the junction of two semi-conductors. Working in reverse, exposing each side of a thermoelectric module to a different termperature creates a current. The corrosion process produces heat, which generates a measureable current. By using a system of two peltier sensors, it is possible to detect corrosion.

Advantages:
- Non-Invasive
- Constant Monitoring
- Low Power
- Low Cost
- Reusable
- Space Efficient

Potential Applications:
- Industrial
- Military
- Aviation
- Transportation
- Pipelines
- Any technology field where corrosion is present
