PURPOSE:To improve reliability of a take-out wire terminal processing section by reducing number of take-out wires to be led out to outside from a level detector, by employing series winding for all the coils for a plurality of level detectors. CONSTITUTION:Top side output coils 34A1...34An, bottom side output coils 34B1...34Bn and exciting coils 34X1...34Xn for all applications ranging from upper limit to lower limit are all wound in series in the same winding direction and to the same coil numbers. And, a top side output coil winding A, a bottom side output coil winding B and an exciting output winding X are led out to a detecting section. By changing connection polarity of the windings A and B which are led out to the outside, the top side output coil and the bottom side output coil are to become able to be changed to differential connection or cumulative connection. As number of connections are reduced by doing so, the reliability becomes able to be improved. |
