System for measuring a physical variable

System for measuring a physical value, in particular for measuring a fill level, having multiple measuring sensors (20), characterized in that capacitive sensors (20) serve as said measuring sensors (20), that an inverting measuring signal amplifier (17;

• 17.1, 17.2) is connected downstream from each measuring sensor (20), one output of a measuring sensor (20) being connected to an inverting input of the inverting measuring signal amplifier (17;
• 17.1, 17.2) connected downstream from the measuring sensor (20) in each case, and said capacitive sensors (20) are formed by a transmitter electrode (S) and multiple receiver electrodes (E;
• E1, E2, E3, E4), the receiver electrodes (E;
• E1, E2, E3, E4) being situated spaced apart from the transmitter electrode
