Abstract
【解決手段】 漏水センサ10は、電気絶縁性を有する線状の心材12と、心材12の表面12aに沿って個別に螺旋状に巻き付けられ、表面12a上で互いに離隔して配置される一対の導線14、16とを備える。これら導線14、16は、それぞれが漏水センサ10の電極として機能し、平常時(非検出時)には、心材12の表面12a上で互いに電気的に絶縁される。漏水センサ10は、両導線14、16の間に液体が介在してそれら導線14、16が互いに電気的に橋絡されたときに、液体を介して両導線14、16に電流が流れることで、液体の存在を感知する。
【選択図】 図1
Description
図面を参照すると、図1は、本発明の一実施形態による漏水センサ10の概略斜視図、図2は、漏水センサ10の断面図である。漏水センサ10は、互いに離隔した一対ないし複数の電極を有し、それら電極間の導通を液体の存在(すなわち漏浸水)として感知する電気式の構成を有する。
