Abstract
A sensor system for sensing pressure of a first fluid (e.g. a liquid and/or gas) comprises an optical sensing fiber that is configured for sensing pressure, and at least one sensor housing embedding the optical sensing fiber. The sensor housing is filled with a second fluid. The sensor housing comprises a non-hermetic pressure transfer medium comprised in the sensor system and positioned in the sensor housing such that a pressure of the first fluid can be transferred via the pressure transfer medium onto the second fluid towards the optical sensing fiber for determining based thereon a pressure of the first fluid.
