Claim Text:
1. A sensor arrangement, in particular for contactless measurement, comprising: a signal generator, which is connected to a first electrode; a first detector, which is connected to the first electrode, and which is designed to measure a first signal and for a capacitive measurement by means of the first electrode; and a second detector, which is connected to a second electrode, and which is designed to measure a second signal and to perform a capacitive measurement by means of the first and second electrodes, wherein the first electrode is connected to the first detector and the signal generator by means of a first switch, wherein the signal generator is connected to the second detector by means of a second switch, and wherein the second detector has a further detection amplifier, to which the second signal and a third reference signal can be supplied, and which detection amplifier provides a third detection signal depending on the second signal and the third reference signal.
