Abstract
A measurement system including: a radial external hole on a cover of a railway axle-box on the side of an edge of the cover facing towards a rolling bearing of the axle-box; a smaller axial hole made on the edge of the cover facing towards a ring of the bearing and opening in the radial hole; a cup-shaped body accommodated in the radial hole; a fork shaped spring integrally carried by a bottom wall of the cup-shaped body, projecting in front of the axial hole; a temperature probe slidingly accommodated within the axial hole and including a tubular element incorporating an electrical temperature sensor and an electric cable protruding from a first end of the tubular element accommodated within the cup-shaped body; and an abutting element removably coupled to the first end to cooperate with the spring, which pushes a second end of the probe out of the axial hole.
