Abstract
A method and apparatus is disclosed for correlating signals generated by a sensor with a position of a plurality of rotating blades to determine turbine blade tip clearance and measurements. The sensor may be positioned in the housing of a turbine, and may be used to determine a radial clearance between the tips of a plurality of rotating turbine blades and a housing during turbine testing and/or operation. A method for using a plurality of sensors separated by a known distance is also disclosed. Other embodiments are disclosed and claimed.
