CORROSION-PREVENTION-PERFORMANCE DEGRADATION DETECTION SENSOR, HOT WATER SUPPLY AND HEATING SYSTEM, AND FACILITY EQUIPMENT |
摘要 |
An anticorrosion performance degradation detection sensor (10) for detecting inclusion of a corrosive factor in a solvent to which a corrosion inhibitor for inhibiting corrosion of an anticorrosion target material is added includes a detection electrode (1), a counter electrode (2), and a power supply (4). The detection electrode (1) reacts with a corrosion inhibitor dissolved in the solvent to form on a surface thereof an electrode surface coating that inhibits corrosion. The counter electrode (2) is disposed to face the detection electrode (1) with a predetermined distance therebetween. The power supply (4) applies an AC voltage with a predetermined frequency between the detection electrode (1) and the counter electrode (2), and performs a voltage operation that promotes decomposition and reformation of the electrode surface coating. The detection electrode (1) detects inclusion of the corrosive factor in the solvent based on a change in an impedance response by the applied AC voltage with the predetermined frequency before and after the voltage operation that promotes decomposition and reformation of the electrode surface coating. |
