Abstract
A circuit arrangement with low sensitivity to faults and few components has a first resistor connected in parallel to the resistor mat and a second resistor connected in series to the parallel circuit. A controllable voltage regulator, to which a control voltage dependent on the resistance of the resistor mat is supplied, is also connected in parallel to the series circuit. The output voltage of the voltage regulator can be tapped as a voltage divider.
