摘要
A method for characterizing the parameters of a normally occurring turbine exhaust gas temperature profile is provided. From that characterization the characteristics of a filter function to eliminate or significantly reduce the strength of aliased signals from that normally occurring pattern are established. Sensors to provide filtering functions for that purpose include a distributed gradient thermocouple system and a resistance thermometer system. Examples of such sensor systems are disclosed. The method and related sensors improve the detection limits associated with exhaust gas temperature profiles used to monitor, diagnose, and control gas turbines.
