Abstract :
The design and performance of an optically powered and isolated sensor system for inaccessible locations is described. Target applications involve sensing in hostile environments such as those experienced in high voltage power systems. A micropowered conventional transducer, serial 12-bit ADC, and LED transmitter are powered by a small photocell array that converts light from an optical fibre into electrical energy. Data is transmitted from the sensor head via an optical fibre link
