<p>The device (1) has a housing (2) accommodating a pressure sensor unit (11) e.g. piezo resistive, for determining fuel pressure. An alcohol sensor unit (4) is accommodated in the housing to determine alcoholic content e.g. methanol, in the fuel. The alcohol sensor unit comprises a condenser arrangement for impedance spectroscopic determination of the alcoholic content in the fuel. The condenser arrangement is formed as an inter digital structure made of nickel or platinum. A heating element (5) e.g. platinum heating element, is provided in the housing.</p> |
