Wireless telemetry system for a turbine engine

A telemetry system comprising:

• a telemetry transmitter assembly affixed to a seal plate proximate to a rotating component within a combustion turbine engine at a location having an operating temperature up to approximately 450° C.;
• a telemetry transmitter circuit contained within the telemetry transmitter assembly, the telemetry transmitter circuit configured to process electronic data signals indicative of a condition of the rotating component;
• an antenna assembly affixed to the seal plate that is proximate to the rotating component;
• a data transmission antenna contained within the antenna assembly, the data transmission antenna receiving electronic data signals from the telemetry transmitter circuit indicative of the condition of the rotating component;
• and
• an induction power system configured for powering the telemetry transmitter circuit, the induction power system operating within the combustion turbine engine at a location having an operating temperature of approximately 450° C.

A telemetry system for use within a combustion turbine engine, the telemetry system comprising:

• a telemetry transmitter circuit board affixed to a seal plate positioned proximate a turbine blade root and having electronic circuitry configured for receiving electronic data signals from a sensor on the seal plate or the turbine blade and transmitting electronic data signals indicative of a condition of the seal plate or turbine blade within the combustion turbine engine;
• a first data antenna affixed to the seal plate and configured for receiving the electronic data signals transmitted from the telemetry transmitter circuit board;
• a second data antenna affixed to a static seal segment adjacent to the first data antenna and configured for receiving electronic data signals transmitted from the first data antenna;
• at least one primary induction coil assembly affixed to the static seal segment and having a core made of a magnetic nanocrystalline iron alloy or magnetic ceramic, such as ferrites;
• a secondary induction coil assembly affixed to the seal plate proximate the turbine blade and having a core made of the magnetic nanocrystalline iron alloy or magnetic ceramic, such as ferrites;
• and
• wherein the at least one primary induction coil assembly is energized at approximately 150 kHz to approximately 500 kHz so that the secondary induction coil assembly has an operating frequency of approximately 150 kHz to approximately 500 kHz and provides power to the telemetry transmitter circuit board.
