<p>A device for indicating clogging of the fuel filter (1) of internal combustion engines, in particular diesel engines, the filter having an outer casing (2) closed by a cover (3) of amagnetic material, and a filter element (5) which, together with a disc (30) to which it is connected, defines two chambers (6and 7) for fuel entry and exit respectively; the device further includes a pressure sensor (10) sensing the difference between the entry and exit fuel pressure and housed inside the filter casing, and a sensor (21) for generating a signal proportional to the pressure difference which is located outside the filter casing and is not mechanically connected to the pressure sensor.</p> |
