Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung S zur Erfassung eines Messwertes insbesondere einer elektrischen Potentialdifferenz (1) und zur drahtlosen Abfrage des Messwertes. Die vorliegende Erfindung weist eine Reflektionsmodulationseinrichtung (3) auf, deren Ausgangssignal die Reflektionseigenschaften einer Sensorantenne (4) derart bestimmt, dass der Messwert der Potentialdifferenz (1) mittels einer Hochfrequenz-Signale abstrahlenden und wieder empfangenen Abfrageeinrichtung (5) von der Sensorantenne (4) entlang einer Funkstrecke (6) abfragbar ist. Die vorliegende Erfindung zeichnet sich dadurch aus, dass der Reflektionsmodulationseinrichtung (3) eine Modulationserzeugungseinrichtung (2) vorgeschaltet ist, die insbesondere bei einer zeitlich unveränderten elektrischen Potentialdifferenz (1), diese in eine Wechselspannungssignal umwandelt, dass von der Abfrageeinrichtung (5) ohne zusätzliche Energie des Spannungssensors S fern abgefragt werden kann. Die vorliegende Erfindung eignet sich insbesondere zur Erfassung von Beleuchtungsstärken, Drehzahlen oder Drehwinkeln.
