Abstract
A field device for determining and/or monitoring a chemical or physical, process variable in automation technology, which has at least a first electronic or electrical component and a second electronic or electrical component. The first component has an energy transmitting antenna and the second component has an energy receiving antenna. Between the two components a predetermined distance is provided, which sets the first component and the second component apart from one another. The predetermined distance is filled, at least partially, with a dielectric medium. The energy transmitting antenna is so embodied and/or arranged that it supplies the second component with energy continuously or at predetermined time intervals.

11. A field device for determining and/or monitoring a chemical or physical, process variable in automation technology, comprising:
-
at least a first electronic or electrical component space; a second electronic or electrical component; an energy transmitting antenna situated in said space; an energy receiving antenna, associated with said second component; and a predetermined distance, which sets the first component and the second component apart from one another, wherein; said predetermined distance is filled, at least partially, with a dielectric medium; wireless energy transmission occurs over larger distances from said predetermined distance means of resonant oscillatory circuits, the resonant oscillatory circuit of said receiving antenna and the resonant oscillatory circuit of said transmitting antenna are so embodied and arranged that the two have resonant frequencies which are equal to one another; and said energy transmitting antenna is so embodied and/or arranged that it supplies said second component with energy continuously or at predetermined time intervals. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
