Abstract
The present document relates to a pressure sensor comprising a structural element, the structural element comprising a first and second structural part. The sensor further comprises a first cavity being in fluid connection with an exterior of the sensor for establishing a first pressure which is dependent on an external pressure in the first cavity and a second cavity configured to be at a second pressure in use. A deformable structure is deformable dependent on a pressure difference between the first pressure and the second pressure. The sensor comprises a fiber including an intrinsic fiber optic sensor fixed to the structural element and to the deformable structure for providing an optical sensor signal dependent on said pressure difference.
