中文拼音 [yèxīnguāngxiān]
液心光纖
英文
liquid core optical fibers-
Aimed at the present status of detecting oil storage fluid, the article advances a method which utilizes the dramatic feature of optical fiber sensor to develop the optical fiber liquid height meter, and to substitute the manual examination means, and supplements the optical fiber liquid overhead alarm equipment, the optical fiber grating temperature sensor, and uses the network technique to build the optical fiber sensing safety supervisory system to realize the intelligent examination of oil - tank area, thereby avoids or decreases occurrence and the risk of accident, and supplies the reliable guarantee for the big - and - middle - sized tank farm safe production
本文針對儲油液位的檢測現狀，提出利用光纖傳感器的特點研製光纖液位計，取代手工檢測的方法，輔以光纖液位高位報警器，光纖溫度傳感器，並應用網路技術構建光纖傳感安全監測系統，實現石油罐區的智能監測，從而避免或減少事故的發生，降低風險，為大中型油庫的安全生產管理提供可靠的保障。本文首先對安全監測系統中的核心硬體? ?光纖液位計的工作原理及特點進行了介紹。But by the characteristics of the optic fiber grating, the optic fiber grating is not sensitive to the external refractive index and cannot be directly used as gas or liquids sensors without the intermediate material like hydrogel
但是由於光纖布喇格光柵本身的特性，它對外界接觸物質折射率的變化並不敏感，接觸物質折射率的變化不會引起中心波長的偏移，因而無法直接將其作為氣體和液體濃度（折射率）的傳感元件。
