Claim Text:
1. A system for transmitting sensor data from a rotating component of a turbomachine, comprising: a plurality of thermal sensors, each thermal sensor coupled to a corresponding rotatable component within the turbomachine, wherein each thermal sensor generates a discrete analogue signal indicative of temperature at the corresponding rotatable component; a plurality of transmitter assemblies annularly arranged within a carrier shaft and coupled to an end of a rotor shaft of the turbomachine, the plurality of transmitter assemblies comprising a first transmitter assembly and a second transmitter assembly, the first transmitter assembly configured to receive the discrete analogue signals from the plurality of thermal sensors, wherein first transmitter assembly multiplexes the plurality of discrete analogue signals into a single amplifier and an analogue-to-digital converter to generate a single stream of digital data therefrom; and a slip ring assembly electronically coupled to the first transmitter assembly and to a data acquisition system, the slip ring assembly having a plurality of conductive rings, wherein at least one of the conductive rings defines a digital signal path between the first transmitter assembly and the data acquisition system; wherein at least one conductive ring of the slip ring transmits a low speed system clock signal through a respective transmitter assembly of the plurality of transmitter assemblies, wherein the respective transmitter assembly transforms the low speed clock signal to a specified high speed clock value using a high speed clock value for at least one of analogue-to-digital conversion and digital synchronization.
