Huang Yonglin, Ding Chao. An FBG sensor for simultaneous measurement of temperature and pressure[J]. 2012,(1):48-49. DOI: 10.13756/j.gtxyj.2012.01.020.
A new Fiber Bragg Grating(FBG)sensor for simultaneous measurement of temperature and pressure is reported in this paper.A part of a single FBG(about one half of a grating) is securely affixed to an open-loop to form a FBG sensor.When the temperature is raised and pressure applied to the open loop
both the temperature and pressure can be measured simultaneously by using a single FBG.Good linear responses to temperature and pressure are achieved in the measurable temperature range of 22
