摘要:
A pressure sensor for connecting to a detector is provided. The pressure sensor comprises: an optical fibre, having a distal end with a distal plane for sensing pressure, a proximal end for communicating with a patch cord, and an In-fibre Bragg grating (FBG) therebetween a housing, having a distal aperture, a proximal aperture and a bore therebetween, and sized to accept the optical fibre an annular ring, forming a flexible seal between said optical fibre and housing at least distal to the FBG and a holder for retaining the housing. The FBG is housed in the housing such that in use, axial strain is transferred to said In-fibre Bragg grating housed within said housing by pressure exerted on the distal plane.
