Abstract
The invention relates to a sensor circuit for a device performing a safety function, comprising at least two sensors, at least two comparison circuits, each of the comparison circuits being assigned to one of the sensors, and a linking unit for combining logic states (L=0, L=1) of comparison circuit outputs of the comparison circuits to form a circuit output signal, the sensor circuit being configured to scale the comparison circuit output value of at least a first one of the comparison circuits and to feed it back to a measurement input or a reference input of at least a second one of the comparison circuits so that, when the comparison circuit output of the first comparison circuit transitions between the logic states (L=0, L=1), the difference between the measurement signal and the reference signal of the second comparison circuit is reduced or the sign of the difference between the measurement signal and the reference signal of the second comparison circuit is reversed. The invention further relates to a device comprising the sensor circuit and a method for processing measurement values from sensors.
