| titleOfInvention | Oil detection sensor |
| abstract | PURPOSE:To increase the detection sensitivity of the sensor and to cope with even leakage of a small mount of oil, etc., by arranging an oil absorbing material on a detection surface. CONSTITUTION:An oil absorbing layer 12 absorbs on oil, and measurement light emitted from an incidence fiber 3 is passed through a lens in the connector 11 on the side of an incidence surface 6 and reflected totally by a reflecting surface 5, converged by the lens of the connector on the side of a projection surface 7, and guided to a projection fiber 4, so that it is confirmed that the detection surface 10 is not covered with oil. If oil leaks by being mixed with water owing to an unexpected accident, etc., the oil absorbing layer 12 absorbs the oil selectively without absorbing the water, so the detection surface 10 contacts the absorbed oil. Then the detection surface 5 of the sensor 1 enters a partial reflecting state because the oil which contacts and covers the sensor 1 is larger in refractive index than air contacting it normally. Consequently, reflected light which is guided to the projection fiber 4 decreases in intensity level and a photodetection part detects the oil leakage. |
