Abstract
The invention relates to a fiber-optically coupled measuring device which has an optically energized transducer section which produces signal information in an optical form, the energy supply for the transducer section and the signal information therefrom being transmitted via a light guide fiber. The signal information is transmitted to a receiver at a location remote from the transducer section, the signal information being modified in response to electrical signals fed to a light emitting component of the transducer section.
