Title:
LIQUID LEVEL DETECTOR
Document Type and Number:
WIPO Patent Application WO/2015/115219
Kind Code:
A1
Abstract:
Provided is a liquid level detector that makes it possible to verify deviation in a magnet incorporated in a holder. A liquid level detector (F) is provided with a holder (2) that rotates in accordance with the displacement of a float corresponding to liquid level variation, a disc-shaped magnet (2a) that is fixed to the holder (2) and rotates with the holder (2), and a magnetic detection element (3) that detects changes in magnetic force accompanying the rotation of the magnet (2a). The holder (2) is provided with holes (2c) through which a portion of the magnet (2a) is exposed. Further, three or more holes (2c) through which a portion of the peripheral portion of the magnet (2a) is exposed are provided, and these three or more holes (2c) are provided roughly evenly along the circumference of the magnet (2a).
