A sensor () for monitoring cathodic protection (CP) levels, i.e. cathodic protection potential and current capacity, the sensor being arranged to perform measurements of galvanic current and polarized potential between, on one hand, a reference object and, on the other hand, one of: i) a sacrificial anode () and ii) a protected component (). The sensor comprises a reference electrode () in electrical and electrochemical contact with a metal sensing element () which has a defined surface area (') exposed to an electrolyte, the sensing element electrically coupled to one of the sacrificial anode () or the protected component () via a resistor () and a switch ().

Real-time cathodic protection integrity monitoring sensor, system and method

A method for evaluation of deleterious phase content and distribution in stainless steels and nickel-based alloys based on the correlation between measured open circuit potentials and volume fraction of deleterious phases is disclosed, in conjunction with a portable equipment and apparatus for carrying out the method.
