ABSTRACT:
A system for monitoring the temperature of a plurality of turbine blade shroud segments includes indicia carried by each shroud segment. A sensor produces input signals in response to the indicia. A temperature sensor measures the temperature of the sensor producing the input signals. A first circuit, responsive to the temperature sensor, corrects the input signals to compensate for the effects of temperature on the sensor. A second circuit determines the temperature of each shroud segment based on the corrected input signals.
