Anti-scaling electrode type conductive liquid level sensor and conductive liquid level detection device comprising same

The invention discloses an anti-scaling electrode type conductive liquid level sensor and a conductive liquid level detection device comprising same. One end of each liquid level detection metal electrode of the sensor is exposed and suspended, and the other end of each liquid level detection metal electrode serves as a signal line connecting end to be wrapped and fixed in the insulating part in aliquid-tight isolation mode. Electrode string resistors are adopted to form a series voltage division branch and then are connected in parallel to form a multi-signal line to single-signal line series-parallel connection resistor voltage division signal transmission circuit, so that the cost and wiring difficulty of a plurality of signal lines can be reduced. The detection excitation power supplyis an alternating-current power supply or a numerical control gap excitation type direct-current power supply or a pulsating direct-current square-wave power supply, so that the problem that each electrode is not scaled or le
