Abstract:

Gas turbine is one kind of the core equipment widely applied to many fields such as aviation, energy, sea and land traffic. The real-time monitoring of various environmental parameters in the process of gas turbine work (such as temperature, pressure etc.) can further improve the structure of gas turbine, improve efficiency, reduce emissions and reduce maintenance costs. A new recently developed sensing system based on micro electro mechanical system (MEMS) technology scores high marks in harsh environment (high-temperature,high-pressure), especially has a great potential for application in the monitoring of various environmental parameters of the gas turbine which is the representative of large mechanical and electrical equipment working in harsh environment. In this paper, the sensing technology in harsh environment, wireless signal transmission technology and the implementation scheme of SiC wireless MEMS sensing system are introduced, reviewed and discussed, and the wireless MEMS sensing system application in gas turbine and harsh environment such as gas turbine is overlooked.

Key words: gas turbines, wireless MEMS sensing system, real-time monitor, harsh environment, high-temperature, high-pressure
