ABSTRACT:
An electric liquid level detector of the condenser type comprises an electrode assembly including a pair of electrodes to be submerged into the oil within a liquid container, an electric circuit assembly provided with an electric detecting circuit for generating an output signal indicative of the level of remaining oil in dependence upon an electro-static capacity between the electrodes, and a flexible tubular guide member of conductive material fixed at its one end to the electrode assembly and at its other end to the electric circuit assembly. The guide member is provided therein with an elongated partition plate of conductive material grounded together with the guide member, and the electrodes are connected to the detecting circuit by means of a pair of insulated electric wires extending through a pair of elongated spaces subdivided by the partition plate in the guide member.
