FUEL FILTER WITH FILTER RECOGNITION |
摘要 |
The invention relates to a fuel filter comprising a housing, an interchangeable filter cartridge that is located in the housing, a water collection chamber and a water level sensor. Said water level sensor has two electric conductors, which can be electrically interconnected by means of water if there is a correspondingly high water level. The filter is provided with a switching element that can move between a contact position and an interruption position, said switching element making contact with the two conductors in the contact position and the contact between the switching element and at least one of the two conductors is interrupted when the switching element is in the interruption position. The electric resistance that occurs between the two conductors has a first value, when the switching element is in the first contact position and a second value that differs from the first, if the switching element is in the interruption position. |
