Beschreibung
Zusammenfassung:	A fiber optic sensor unit (1a) for detecting a mechanical force acting on a rail (15) comprising at least a first sensor fiber (2, 3), a first elongated fiber optic strain sensor (4) and a second elongated fiber optic strain sensor (5), wherein the first sensor fiber (2)comprises the first strain sensor (4), is characterized in that the at least one sensor fiber (2, 3) is attached to a sensor plate, and that the first fiber strain sensor (4) and the second strain sensor (5) are arranged in an x-type or geometry, wherein the first strain sensor (4) and the second strain sensor (5) are arranged in an angle of 60° to 120° , in particular of 90°, to each other. Measurements with increased amplification of the measurement signal and improved raw data can be made.
