Abstract

Fibre-optic pressure sensor for measuring a fluid pressure, the sensor comprising: - an elongated base frame having a longitudinal axis; - a first pressure compartment having a variable size that is coupled to the elongated base frame, wherein the first pressure compartment comprises an input arranged to receive a fluid, the pressure of which is to be measured, wherein a movable outer end of the first pressure compartment is movable within the elongated base frame parallel to the longitudinal axis between a retracted position and an extended position; - a biasing system arranged for urging the movable outer end of the first pressure compartment in a direction towards the retracted position; - an optical fibre comprising a first connected section that is connected to the elongated base frame and a second connected section that is arranged to move upon a movement of the movable outer end of the first pressure compartment, wherein the optical fibre further comprises a first suspended section that is suspended in between the first connected section and the second connected section; - a transfer member comprising a first pivotable arm that is pivotally coupled to the elongated base frame at a hinge point, wherein the movable outer end of the first pressure compartment is coupled at a coupling point, at a distance from the hinge point, to the first pivotable arm, such that a movement of the movable outer end of the first pressure compartment causes a pivoting movement of the first pivotable arm; wherein the transfer member further comprises a fibre connecting section whereto the second connected section of the optical fibre is fixed, wherein the fibre connection section is arranged to move, upon a movement of the first pivotable arm, in at least a direction parallel to the longitudinal axis, such that the pivoting movement of the first pivotable arm causes a stretching or shortening of the first suspended section of the optical fibre.
