Sensor para la monitorización de la corrosión mediante medidas de impedancia y ruido electroquímicos y de resistencia a la polarización y uso del mismo

The present invention relates to a sensor that is able to perform joint measurements of electrochemical impedance and noise and of resistance to polarisation, enabling continuous, reliable control of general and localised corrosion processes. This monitoring system is suitable for low- and high-temperature industrial or process atmospheres in which a melted, gas or liquid phase is present, be it, for example, from metals, alloys, salts or glass, all in melted state.
