Claims (1)
- 一対の櫛歯形状の検出電極を互いに間隔をあけて噛み合わせるように基板に配置して設けるとともに、液体に接触させて前記検出電極の静電容量を検知することにより液位液質を検出する検出素子と、この検出素子を収納する筒状ケースと、前記筒状ケースが接合される本体ケースとを組み合わせて設け、前記筒状ケースを前記液体に浸漬させてなる外装ケースとを備え、前記検出素子は、液位を検出する液位用検出電極と液質を検出する液質用検出電極とを有し、基板の表裏面の一方の面に前記液位用検出電極を配置し、前記基板の表裏面の他方の面に前記液質用検出電極を配置するとともに、筒状ケースには、その一部を切り欠いて切欠部を設け、かつこの切欠部に嵌り合う蓋部を設け、前記蓋部と切欠部で前記基板の端部を挟持して前記基板を筒状ケースに固定する構成とした液位液質センサ。
