ABSTRACT:
A component for use in a combustion turbine (10) is provided that includes a substrate (212) and an abradable coating system (216) deposited on the substrate (212). A planar proximity sensor (250) may be deposited beneath a surface of the abradable coating system (216) having circuitry (252) configured to detect intrusion of an object (282) into the abradable coating system (216). A least one connector (52) may be provided in electrical communication with the planar proximity sensor (250) for routing a data signal from the planar proximity sensor (250) to a termination location (59). A plurality of trenches (142) may be formed at respective different depths below the surface of the abradable coating system (216) with a planar proximity sensor (250) deposited within each of the plurality of trenches (142). A processing module (34) may be programmed for receiving data from the planar proximity sensor (250) and calculating a clearance between a row of blades (18,19) within a combustion turbine and the planar proximity sensor (250). The processing module (34) may control a clearance between the row of blades (18) and a ring segment (284) based on data received from the planar proximity sensors (250).
