Paper Abstract

This paper presents the basic principle and system research of touching type self-emission high tenperature fiber optic temperature sensor based on black—body radiation. In this system ,we solved the problem of "length effect" using a optical subsystem, developed superlower current of 10-10A, improved the resolution of the A/D converter by adding a noise source. This system can continuously measure the temperature from 300°C to over 1200°C with the precision of 1°C.
