PROBLEM TO BE SOLVED: To quickly and efficiently measure a disc wheel clearance in a turbine, thereby correctly and quickly performing positioning of the turbine blade and the diaphragm.;SOLUTION: A comb-shaped disc wheel clearance measurement sensor 5 is provided to sandwich a turbine blade 1 of a steam turbine and to be placed along a clearance between the turbine blade 1 and a lower diaphragm 2. A plurality of clearance measurement elements 5a attached on a lower face of the disc wheel clearance measurement sensor 5 measure a plurality of disc wheel clearances between the turbine blade 1 and the lower diaphragm 2.;COPYRIGHT: (C)2014,JPO&INPIT
