| 摘要 | 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. | ||

| 主权项 | 1. A sensor arrangement, comprising: a current regulator; a reference resistance; a feed current scaler; and a sensor element comprising an internal resistance, wherein the internal resistance of the sensor element and the reference resistance comprise a predetermined ratio with respect to each other; wherein the current regulator is implemented to provide a reference current by the reference resistance and, in response to an interference influence-conditioned change of the reference resistance, change the reference current such that the voltage decreasing across the reference resistance remains in a predetermined range around an applied set voltage; wherein the current regulator is further 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; and wherein the feed current scaler is implemented, based on the feed current, to supply a scaled feed current into the sensor element to scale a voltage decreasing across the internal resistance of the sensor element according to the scaling of the feed current. | ||
