Abstract: A kind of lightweight optical fiber output passive retractable current sensor was developed. This paper gave its basic structure and expounded each part’s working principle. This sensor used the passive structure with the highly compositive microcontroller, C8051F33 0 embed to carry out sampling and data analysis. The data transmission adopted digital mode via optical fiber. The high safety performance protective circuit was added, as well as the signal feedback circuit. The experiment verifies that this sensor meets the requirements of the design completely, with the advantages such as small volume, strong antijamming capability, direct digital data output etc, and it is easy to install and maintain with high speed sampling.
Key words: passive; optical fiber; sensor; retractable; draw-out power
