Abstract
A device for transmitting measured values to a remote location characterized by the sensor device applying an output voltage control to an electro-optical modulator to create a light signal from a source of light received from an optical divider for conducting back to the remote location and the energy for the sensor device being supplied as light energy from a remote location to the optical divider whose other output beam is converted into electrical energy by a transducer associated with the sensor device.
