Coaxial Stub Resonator for Online Monitoring Early Stages of Corrosion
Here we demonstrate the proof-of-principle of a new type of flow-through sensor to assess the corrosion rate of metal surfaces. The method can be applied to all situations where metals are exposed to a corrosive (fluidic) environment, including, for instance, the interior of pipes and tubes. Our sensing device is based on the operating principle of a quarter wave length open-ended coaxial stub resonator. The method described here can be applied for on-line monitoring corrosion.
