Abstract
A hub unit adapted for use in a monitoring system that monitors engine performance parameters of a gas turbine engine. The hub unit includes a housing, at least one signal conditioning circuit board within the housing and adapted to receive the analog sensor outputs from the sensors, and a control circuit board within the housing, connected to the signal conditioning circuit board, and adapted to produce digital data corresponding to analog sensor outputs. The signal conditioning circuit board multiplexes a plurality of the analog sensor outputs generated by the sensors 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.
