Abstract: An optical pressure sensor device (1) comprises: a chamber (2) filled with pressure transfer medium and having at least one window (4) transparent to pressure waves; an optical fibre (7) with a Fibre Bragg Grating (8); a first pressure-sensitive mounting assembly (100) arranged within the chamber, holding the optical fibre; a second pressure-sensitive mounting assembly (200) arranged within the chamber, holding the optical fibre. The first pressure-sensitive mounting assembly, the second pressure-elm.) sensitive mounting assembly, and a static pressure compensation assembly (300) comprise pairs of bellows arranged on opposite sides of the fibre (7). The bellows (310, 320) of the static pressure compensation assembly have their interior in fluid communication with the pressure transfer medium in the chamber via a choke channel (314, 324), and have very low static stiffness.
