本电路可自动检测船身舱底有无积水并用自动或人工的方式进行排水。电路核心部分为由 LM1830及其外围电路组成的积水检测器。IC1内部在工作时能产生交流信号通过积水区的两只探头,并利用比较探头间电阻与其内部基准电阻的原理来检测是否有积水 The circuit can automatically detect the hull bilge water and use automatic or manual drainage. The core of the circuit is a water detector composed of the LM1830 and its peripheral circuits. IC1 internal work in the generation of AC signals through the two probe water area, and by comparing the resistance between the probe and its internal reference resistor to detect whether there is water
