LEAKED OIL SENSOR AND A MANUFACTURING METHOD THEREOF, CAPABLE OF MEASURING A SORT AND A RANGE OF LEAKED OIL IN THE FIELD

摘要

PURPOSE: A leaked oil sensor and a manufacturing method thereof are provided to discharge oil absorbed in the leaked oil sensor by storing the leaked oil sensor in clean water for predetermined time, thereby reusing the leaked oil sensor.;CONSTITUTION: A leaked oil sensor(1) comprises a silicon rubber(2), and a strain gauge(3). The silicon rubber absorbs leaked oil. The strain gauge is embedded in the inside of the silicon rubber, thereby measuring a volume change of the silicon rubber. The silicon rubber becomes hardened by injecting liquid silicon on the outer circumference of the strain gauge.;COPYRIGHT KIPO 2013
