摘要: 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.
