The invention relates to a strain gauge arrangement (1), in particular for an axle counter (91), comprising at least one strain sensor element (5), in particular an optical fibre (6) having a fiber Bragg-grating (6a, FBG), a carrier (2) on which the strain sensor element (5) is secured, and a structure (4) that is to be monitored, in particular a railway line, on which the carrier (2) is secured.At least one part of the carrier (2) is maintained in an elastically deformed state by the structure (4) when the carrier (2) is secured to the structure (4). The invention is characterized in that the carrier (2) is formed from a first carrier piece (T1) and a second carrier piece (T2), which lie opposite one another at a distance from one another, and in that the strain sensor element (5) comprises at least one first fixing point (7) which is fixed to the first carrier piece (T1), and at least one second fixing point (8) which is fixed to the second carrier piece (T2), and a middle section (5a) mounted between the f
