ABSTRACT:
A sensor including at least one electrode (3, 4) which is made of electrically conductive plastic and is connected to one end of an electrical conductor (5, 6). The electrode (3, 4) and conductor (5, 6) are surrounded by an insulating housing (2, 22), except that the electrode has an exposed surface (7, 8) for contacting an aggressive or corrosive medium inside the housing. The other end (11, 12) of the electrical conductor protrudes from the housing (2, 22). The housing (2, 22) is made of an electrically insulating plastic material which is joined to the electrode (3, 4) in a sealed manner. In a preferred embodiment, the housing (2, 22) forms a valve seat and seal for a bottom drain valve of a fluid container.
