<P>PROBLEM TO BE SOLVED: To provide a system for monitoring performance parameters of an apparatus operating at an elevated temperature, such as a gas turbine engine. <P>SOLUTION: The system 10 includes sensors 20 for sensing the performance parameters and generating analog sensor outputs, at least one hub unit 14 mounted sufficiently close to the apparatus so as to be subjected to a first temperature in excess of 125°C, a collector unit 16 subjected to a second temperature of less than the first temperature, and a distributor computer unit 18 subjected to a third temperature of less than the second temperature. The hub unit 14 has control and signal conditioning circuit boards 22 and 24 that operate together to condition the analog sensor outputs of the sensors 20 and produce corresponding digital data. The collector unit 16 transmits the digital data from the hub unit 14 to the distributor computer unit 18, which processes the digital data to assess the performance parameters of the apparatus. <P>COPYRIGHT: (C)2012,JPO&INPIT |
