A sensor system () and method for monitoring a powertrain () having a drive shaft (). The sensor system () comprises an optical fibre () with a strain sensitive element (). According to one aspect, a connection structure () is configured to hold at least a part of the optical fibre () with the strain sensitive element () at a radial distance (R-R) remote from the drive shaft () for amplifying the strain (S) on the strain sensitive element () with respect to the strain () on the drive shaft (). According to a further aspect, at least three respective lengths of one or more optical fibres follow parallel, e.g. helical, paths with respect to each other to distinguish different strain forces.
