Abstract

The invention relates to a sensor (100) for detecting at least one measurable measuring variable of a medium in a pipe (102), wherein the sensor (100) comprises at least one expandable optical fiber (106) that can be evaluated by an evaluation device (104), said optical fiber being arranged in the pipe (102) in order to determine the measuring variable.
