光纤检漏系统

Optical Fibre Leak-Detection System

本文介绍一种新型的光纤检漏系统,通过对待测件内气体状态分析,确定采用比较法充压检漏技术和先进的光纤技术,研制成既具有高检测灵敏度又稳定可靠的检漏系统。该系统已成功地用于工业生产中,对水库大坝仪器实现了在线充压检漏,保证产品质量。

In this paper, a new optical fibre leak-detection system is presented with high detection sensitivity, reliable and stability. Through the study of the gas state in the detected samples, the system is designed by making use of the pressure comparison leak-detection technique and optical fibre sensing technique. The system has successfully been used in industry production of the instruments for the storage dams.
