FENG Fei, QIAO Xue-guang, JIA Zhen-an, et al. Techniques of fibre grating sensors by high temperature and high pressure[J]. 2008, (6): 9-11. DOI: 10.13873/j.1000-97872008.06.010.
Along with optical fiber grating sensor’s widespread application
it is a important application direction in industrial environment of high temperature
high pressure
strong electronmagetic interference and so on.Optical fiber grating high temperature sensor and high pressure sensor which apply to the oil gas mine are introduced.The existing some models technical plans and the sensor structural design are elaborated.Its characteristic is analyzed and its application prospect is forecasted.
