Abstract

An instrumented component (18, 19) for use in various operating environments such as within a combustion turbine engine (10). The component (18, 19) may have a substrate, a sensor (50, 94, 134) connected with the substrate for sensing a condition of the component (18, 19) during operation of the combustion turbine (10) and a connector (52, 92, 140) attached to the substrate and in communication with the sensor (50, 94, 134) for routing a data signal from the sensor (50, 94, 134) to a termination location (53). The component (18, 19) may include a wireless telemetry device (54, 76, 96) in communication with the connector (52, 92, 140) for wirelessly transmitting the data signal. Recesses (114, 116) may be formed with a root portion (112, 132) of components (18, 19) within which wireless telemetry device (54, 76, 96) may be affixed.
