A sensor system having a sensor unit for detecting a measured variable, and an evaluation unit, which are interconnected via at least one or a plurality of connection line(s), the sensor unit having a sensor, which is connected to a supply voltage, and includes a signal output for a measuring signal that is a function of the measured variable, the evaluation unit having a voltage meter to detect the status of the measured variable as a function of a potential, the sensor unit including a first resistive circuits connected to the sensor, and the evaluation unit including a second resistive circuit connected to the voltage meter. The first and the second resistive circuits are coupled to one another via at least the sensor line and forming a resistor network. The first and the second resistive circuit are configured so that, in a fault-free state of the one or the plurality of connection line(s), the voltage meter detects one or a plurality of measuring potential(s) in one or a plurality of defined measuring potential range(s) as a function of the measured variable, and, in a fault case, it detects a measuring potential that lies within a fault potential range. The first and the second resistive circuits are dimensioned so that the fault potential range lies outside of the one or the plurality of defined measuring potential range(s). |
