Sensor device for measuring a fluid pressure, and method for manufacturing a sensor device

A sensor device at least for measuring a fluid pressure, having a base body and having a fibre-optic sensor unit which comprises at least one sensor element which is in the form of a light-conducting fibre and which extends along a longitudinal extension of the base body at least in sections at least substantially helically around the base body, the sensor device further having a transmission unit which is arranged in at least one measuring range around the base body and the at least one sensor element and is configured to receive a fluid from an environment and to transmit a fluid pressure to the fibre-optic sensor unit for deformation of the at least one sensor element,

• wherein the at least one measuring range is designed as a region of the at least one sensor element in which the fluid pressure is detected,
• wherein the transmission unit comprises at least one receiving element which is formed from a porous material and a support unit, wherein the support unit is configured to shield the at least one receiving element at least in regions against deformation caused by a mechanical action of force from an outside of the transmission unit,
• wherein the support unit is configured to conduct the fluid from the outside through the support unit to the at least one receiving element,
• wherein the support unit is provided with recesses which are permeable only to fluids,
• wherein the at least one receiving element is permeable for the fluid.
