Abstract: 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.

Abstract: A sensing device for detecting a physical parameter exemplified by pressures, strains, temperatures, indices of refraction, and combinations thereof. The sensing device comprises a probe having a housing for sealably mounting therein an optical fibre. The optical fibre is provided at its distal end with at least two spaced apart fibre Bragg gratings. The proximal end of the probe is engagable with a holder, and is in communication with fibre Bragg grating interrogation systems. Spacers and seals may be provided about the optical fibre between the fibre Bragg gratings. An orifice may be provided and sealed with a resilient membrane to provide a contained airspace around each fibre Bragg grating. The contained airspace may be optionally filled with a fluid or a gas.
