High sensitivity fiber Bragg grating (FBG) sensor based on hollow core silica tube (HCST) sensitization for gas pressure and temperature discrimination

A fiber Bragg grating (FBG) based sensor is proposed for the measurement of gas pressure under extreme tem-perature condition. Two FBG sensors of different cladding diameters are encapsulated and sealed in a fine hollow-core silica tube (HCST) by using a high temperature resistant ceramic adhesive (...
