Abstract
A sensor device, at least for measuring a fluid pressure, has a base body and has a fibre optic sensor unit which includes one or more sensor elements(s) which is in the form of a light conducting fibre and which extends along a longitudinal extension of the base body at least substantially helically around the base body. A transmission unit, which is arranged in at least one measuring range around the base body and the one or more sensor elements(s), receives a fluid from an environment and transmits a fluid pressure to the sensor unit for a deformation of the at least one sensor element.
