Abstract

In a device for monitoring the distance of the front surfaces (3, 4) of rails (1, 2), for example, in connection with expansion joints or supporting structures in which the rails are subjected to multi-axial load, one rail (2) is connected with at least one plate member or, respectively, damping element (6) extending in transverse relation to the longitudinal direction of the rail, noting that the axes (8) of measuring sensors (7) are oriented in normal relation to the plate members (6) and that the rail (2) is supported in proximity of the fixing points for the plate members (6) in a sliding manner and in a manner reliably preventing swivelling out of the moving direction to be measured.
