PROBLEM TO BE SOLVED: To transfer data from rotating instrumentation of a turbomachine to a stationary data acquisition system.SOLUTION: A system includes a plurality of thermal sensors coupled to corresponding rotatable components within a turbomachine, each thermal sensor generating a discrete analogue signal indicative of temperature. A plurality of transmitter assemblies are coupled to an end 36 of a rotor shaft 22 of the turbomachine. The plurality of transmitter assemblies include a first transmitter assembly and a second transmitter assembly. The first transmitter assembly is configured to receive the discrete analogue signals from the plurality of thermal sensors, multiplex 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. The system also includes a slip ring assembly 108 having a plurality of conductive rings, where at least one of the conductive rings defines a digital signal path between the first transmitter assembly and a data acquisition system 110.SELECTED DRAWING: Figure 1 【課題】ターボ機械の回転計装器からのデータを固定データ収集システムに伝送する。【解決手段】システムは、ターボ機械内の対応する回転構成要素に結合され、温度を示す離散的アナログ信号を各々が生成する複数の熱センサを含む。複数の送信器組立体は、ターボ機械のロータシャフト２２の端部３６に結合される。複数の送信器組立体は、第１の送信器組立体及び第２の送信器組立体を含む。第１の送信器組立体は、複数の熱センサから離散的アナログ信号を受け取り、複数の離散的アナログ信号を多重化して単一増幅器及びアナログ−デジタルコンバータに送り、これから単一のデジタルデータストリームを生成するよう構成されている。本システムはまた、複数の導電性リングを有するスリップリング組立体１０８を含み、導電性リングのうちの少なくとも１つが、第１の送信器組立体とデータ収集システム１１０との間にデジタル信号経路を定める。【選択図】図１
