A monitoring device for monitoring the temporary rail connection of two rail sections of one rail, and a rail connection system with such a monitoring device.

摘要

The monitoring device (9) has a first fixing element (22) that can be fixed to the first rail section (4) in order to monitor the temporary rail connection portions of the two rail sections (4, 5). And a second fixing element (24) that can be fixed to the second rail section (5). The monitoring device (9) further includes a first spacing sensor (30) for measuring the first spacing (d) between the fixed elements (22, 24) and a first fixed element (22). It includes a second spacing sensor (31) for measuring a second spacing (a) between the temporary rail connection and the first clamping device (15). The monitoring device (9) enables reliable monitoring of the temporary rail connection.
