    • A metal rod-shaped element for a liquid detecting device is essentially cylindrical and has first and second ends. In at least one length, starting from the second end, the element has an isolating coating and an electrode strip is provided which extends along a longitudinal axis of the element. The electrode strip is not electrically connected to the element and the strip comprises a high impedance material. Two flattened sections are provided where the metal of the element lies openly. In a cross sectional view the electrode strip is situated between the two flattened sections. A first contact mechanism is provided in order to establish, in the range of the first end, an electrical contact to the rod-shaped element, and a second contact mechanism is provided in order to establish, within the range of the first end, an electrical contact to the electrode strip.
    • 用于液体检测装置的金属棒状元件基本上是圆柱形的并且具有第一和第二端。 在至少一个长度上,从第二端开始,元件具有隔离涂层,并且提供沿着元件的纵向轴线延伸的电极条。 电极条不与元件电连接,并且条带包括高阻抗材料。 提供两个扁平部分,其中元件的金属公开地放置。 在横截面图中,电极条位于两个平坦部分之间。 提供第一接触机构,以在第一端的范围内建立与杆状元件的电接触,并且提供第二接触机构,以便在第一端的范围内建立一个 电接触到电极条。
