Abstract

Abstract Translated from German Zur Messung hochfrequenter Wechselfelder, insbesondere in Kernspin-Tomographen, wird erfindungsgemäß das Meß­signal in einem Signalaufnehmer (10) in ein entspre­chendes Ultraschall-Signal umgewandelt, das zu einem Empfänger (30) übertragen und dann wieder in ein elek­trisches Signal umgewandelt wird. Die Übertragungs­stecke (20) enthält keine metallischen Komponenten und bewirkt somit auch keine Feldstörung. To measure high-frequency alternating fields, in particular in nuclear spin tomographs, the measurement signal is converted according to the invention in a signal pickup (10) into a corresponding ultrasound signal, which is transmitted to a receiver (30) and then converted back into an electrical signal. The transmission link (20) contains no metallic components and therefore does not cause any field interference.
