Abstract
A liquid level sensorcomprises a sleevedisposed so as to extend in the vertical direction, a floatconfigured so as to move along said sleeve according to fluctuation of liquid level, a resistor string, a plurality of grounding meansdisposed inside the sleeveand a liquid level signal output meansto take out an electric signal detected between a positive electrode side end partand a junction part grounded by the grounding meansas a liquid level signal that is a signal corresponding to the liquid level, and further comprises a warning signal output meansto output a warning signal when the floatis located within a predetermined distance from a warning position that is a predetermined position within a movable range of the float. Thereby, a compact and reliable liquid level sensor is realized.
