| 摘要 |
A system for monitoring performance parameters of an apparatus operating at an elevated temperature, such as a gas turbine engine. The system includes sensors for sensing the performance parameters and generating analog sensor outputs, at least one hub unit mounted sufficiently close to the apparatus so as to be subjected to a first temperature in excess of 125° C., a collector unit subjected to a second temperature of less than the first temperature, and a distributor computer unit subjected to a third temperature of less than the second temperature. The hub unit has control and signal conditioning circuit boards that operate together to condition the analog sensor outputs of the sensors and produce corresponding digital data. The collector unit transmits the digital data from the hub unit to the distributor computer unit, which processes the digital data to assess the performance parameters of the apparatus.
