| titleOfInvention | Fuel / moisture detection sensor in oil |
| abstract | (57) Abstract: The present invention relates to a sensor for detecting a fuel / moisture content in oil, and more particularly, to transmitting an ultrasonic wave at two points having different temperatures to determine a fuel mixing amount and a moisture content present in a very small amount in oil. The present invention provides a sensor for detecting the amount of fuel and moisture in oil, which receives a reflected wave, measures a difference in sound speed depending on temperature, and can detect a small amount of fuel mixed in and an amount of moisture. SOLUTION: This sensor measures a small amount of fuel mixed in water and the amount of water present in oil, and transmits ultrasonic waves into the oil at two points having different oil temperatures, and generates reflected waves from a sensor reflection surface. Receive and measure the difference in sound speed due to temperature, The fuel mixing amount and the moisture amount are detected from the relationship map between the sound velocity difference, the fuel mixing amount, and the water amount obtained in advance, and the minute fuel mixing amount and the water amount are reduced to 2 to 3 vol. %, And the two points having different oil temperatures are separated by at least 30 ° C. |
