<P>PROBLEM TO BE SOLVED: To solve a problem that housing method of a coil and capacitor and insulation method of the coil are becoming problematic resulting in influence to the cost caused by overall miniaturization in a water level sensor that includes a diaphragm, core, coil, capacitor, etc. and detects the water level according to variation of the oscillation frequency of the coil and capacitor. <P>SOLUTION: A bobbin is prepared and the coil and capacitor are assembled to the bobbin so as to form a bobbin section assembly. The bobbin section assembly is stored inside the frame body to prevent entering of water. Consequently insulation processing of the coil is eliminated, and three components of the coil, the capacitor, and a terminal are connected at one point efficiently. <P>COPYRIGHT: (C)2012,JPO&INPIT |
