MULTI-POINT PRESSURE SENSOR AND USES THEREOF |
摘要 |
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 engageable 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.
