A circuit assembly (34) affixed to a moving part (20) of a turbine for receiving information about a condition of the part and transmitting this information external to the engine. The circuit assembly includes a high-temperature resistant package (34A) that attaches to the part. A high temperature resistant PC board (42) supports both active and passive components of the circuit, wherein a first group of the passive components are fabricated with zero temperature coefficient of resistance and a second group of the passive components are fabricated with a positive temperature coefficient of resistance. The active components are fabricated with high temperature metallization. Connectors (40) attached to the PC board pass through a wall of the package (34A) for communication with sensors (30) on the part and with an antenna (26) for transmitting data about the condition of the part to outside the turbine.

摘要:
In a telemetry system for use in an engine, a circuit structure (34) affixed to a moving part (20) of the engine is disposed for amplifying information sensed about a condition of the part and transmitting the sensed information to a receiver external to the engine. The circuit structure is adapted for the high temperature environment of the engine and includes a differential amplifier (102, 111) having an input for receiving a signal from a sensor (101, 110) disposed on the part. A voltage controlled oscillator (104, 115) with an input coupled to the output of the amplifier produces an oscillatory signal having a frequency representative of the sensed condition. A buffer (105, 116) with an input coupled to the output of the oscillator buffers the oscillatory signal, which is then coupled to an antenna (26) for transmitting the information to the receiver.
