LIQUID AMOUNT DETECTING DEVICE

摘要

A liquid amount detecting device may be provided with a first detector disposed in a first storage part; a second detector disposed in a second storage part; and a connecting cable. The first detector may include: a first float; a first arm; a first magnetic sensor which generates a first analogue signal corresponding to the movement of the first arm; and a first output terminal which outputs a first output voltage value corresponding to the first analogue signal. The second detector may include: a second float; a second arm; a second magnetic sensor which generates a second analogue signal corresponding to the movement of the second arm; a reference terminal; and a second output terminal which outputs a second output voltage value corresponding to an integrated voltage value in which a voltage value indicated by the second analogue signal and the first output voltage value are integrated.
