Title:
液面検出装置及びその製造方法
Document Type and Number:
Japanese Patent JP6519568
Kind Code:
B2
Abstract:
A liquid level detecting device includes the segment electrodes with which the sliding contact is in sliding contact according to the movable body's movement, an output electrode that produces an electrical output corresponding to an electrical resistance between the sliding contact and the output electrode, a resistive element having a higher resistance than the segment electrodes and located across the segment electrodes and the output electrode to be electrically connected thereto, and adjustment electrodes provided on the mounting surface corresponding to the electrode groups respectively. The adjustment electrode is electrically connected to a specific electrode, which is a specific segment electrode in a corresponding electrode group, to have its electrical resistance adjusted in advance with respect to the output electrode. The circuit board includes a cut mark recessed from the mounting surface between the segment electrodes other than the specific electrode in each electrode group and a corresponding adjustment electrode.
