Abstract
The invention relates to a sensor arrangement for determining a tank fill level of a liquid, especially a reducing agent for removing nitrogen from the exhaust gases of an internal combustion engine, which liquid is contained in a tank, at least two electrically conductive measuring electrodes being at least partially embedded in a carrier that is produced of an electrically non-conductive material. The sensor arrangement includes a temperature sensor, especially a resistor with negative temperature coefficient being used as a temperature sensor, which is integrated into the carrier.
