<P>PROBLEM TO BE SOLVED: To provide an electronic hardware capable of operating within a high temperature environment on a gas turbine engine. <P>SOLUTION: A hub unit 14 includes a housing 44, at least one signal conditioning circuit board 24 within the housing 44 and adapted to receive analog sensor outputs from sensors 20, and a control circuit board 22 within the housing, connected to the signal conditioning circuit board, and adapted to produce digital data corresponding to the analog sensor outputs. The signal conditioning circuit board multiplexes a plurality of the analog sensor outputs generated by the sensors 20 to produce an individual multiplexed analog output, and has at least one amplifier with adjustable gain for scaling the analog sensor outputs of the individual multiplexed analog output to produce an individual conditioned multiplexed analog output from which the corresponding digital data are produced. The amplifier and the adjustable gain thereof are controlled by the control circuit board 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
