| Zusammenfassung: | A support (
1
) for a reflective target to be mounted on a turbine casing, which is used in casing bending measurements. The support (
1
) comprises a tube (
2
), which was chosen to ensure a thermal expansion coefficient near zero at the operating temperatures of the casing. The tube (
2
) is located at one end in a steel holder (
3
). In the middle of the tube (
2
) is arranged a metal rod (
9
), which is fixed to the holder (
3
). At the opposite end of the tube (
2
) is an insert (
7
), which has an apertures through which passes the metal rod (
9
). Within the insert (
7
) the metal rod (
9
) is screw threaded so it can be turned to provide always enough tension at all operating temperatures and the metal tube (
9
) is held tight, secure, and has minimal vibration. |
