<p>PROBLEM TO BE SOLVED: To provide an oil deterioration sensor capable of measuring an oil without operation such as resolution and dilution, and capable of detecting deterioration of the oil itself.SOLUTION: An oil deterioration sensor 1 comprises: an ion liquid film 10 including ion liquid and capable of contacting to an oil 2 at least partially during deterioration detection of the oil 2; a sensitive electrode 20 which has a sensitive part 21 covered at least partially by the ion liquid film 10 and configured to sympathize to movement of polar materials from the oil 2 to the ion liquid film 10; a comparison electrode 30 electrically communicated to the ion liquid film 10; and a potential difference meter 40 for measuring potential difference between the sensitive electrode 20 and the comparison electrode 30.</p> |
