Beschreibung
Zusammenfassung:	An active sensor consisting of a measuring module and an interface module comprising at least one first current source, an input line and an output line, wherein the active sensor is supplied with energy via these two lines and the first current source is connected on the output side to the output line and the interface module generates the output signals of the active sensor in the form of current signals, wherein the interface module comprises a current sensing device which senses the load current of the measuring module, and a compensating device which can generate, on an output path connected to the output line, a first compensating current for compensating for amplitude fluctuations in the output current signals in dependence on the sensed load current of the measuring module. Also described is a method for compensating for amplitude fluctuations in the output current signals of an active sensor.
