A device 1 for tracing a profile, for example the cross- sectional profile of a railway wheel 2, 3, comprises a stationary part 11 which supports a first arm 22 and a second arm 23, which arms are interconnected at the ends by means of angle-measuring swivel links 20, 21. One of the arms 23 comprises a free end with a measuring wheel 24 which is adapted to be brought into contact with the profile to be traced. Both the swivel links 20, 21 are electronic angle measuring devices which are connected to a portable computer via an interface circuit. <IMAGE>
