摘要： A liquid level sensing system comprises a permanent magnet mounted in a cylindrical supporting case disposed in a housing and provided with a resistance plate at one end thereof, a reed switch arranged parallel to the permanent magnet and electromagnetic means including an iron core and a coil arranged above the supporting case and on the same axis as the permanent magnet. When the level of the engine oil goes down, the reed switch and the electromagnetic means cause the permanent magnet to vertically vibrate in the supporting case in the axial direction thereof thus causing for example a lamp to flash on and off and indicate the existence of an irregularity. With the construction described above, the system of this invention is capable of sensing an abnormal deterioration of the engine oil in addition to the sensing of the engine oil level.
