Patent ID: 8220990

Claim:
A telemetry system for use in a high temperature environment comprising: a stationary or moving part of a turbine; a circuit assembly affixed to the part of the turbine and arranged to receive information sensed about a condition of the part of the turbine and transmit said received information to a receiver external to said environment, said circuit assembly being adapted for operation in the high temperature environment and comprising: a high-temperature resistant package for housing said circuit assembly and being adapted for attachment to said part; a PC board for supporting both active and passive components of said circuit assembly, said active components being fabricated with high temperature metallization; a retainer affixed to an inside surface of said package for securing said PC board in place within the package; and, connectors attached to said PC board and passing through a wall of said package for supplying power to said circuit assembly and for communication with a sensor on said moving part and an antenna for transmitting data signals outside said environment, said data signals being indicative of the information sensed about the condition of said part.
