Abstract
A sensor arrangement has a current regulator, a reference resistance a feed current scaler and a sensor element having an internal resistance, the internal resistance of the sensor element and the reference resistance having a predetermined ratio. The current regulator is implemented to provide a reference current by the reference resistance and to change the reference current in response to an interference influence-conditioned change of the reference resistance such that the voltage decreasing across the reference resistance remains in a predetermined range around an applied set voltage. The current regulator is implemented to provide a feed current to the feed current scaler and to change a magnitude of the feed current depending on a magnitude of the reference current. The feed current scaler is implemented to feed a scaled feed current into the sensor element to scale a voltage according to the scaling of the feed current.
