In order to monitor radial vibration, thrust position and key phase of compressor shafting in 0.6 m continuous transonic wind tunnel accurately, a shafting monitoring system based on Bently3500 machinery protection system was developed. By Bently3500 configuration, PLC and HMI program designing, the developed continuous online monitoring system was successfully used in wind tunnel testing and compressor commissioning. The debugging results show that: the system fully meets the requirements of compressor shafting monitoring, achieves continuous acquisition, monitoring and logic alarm of shafting working parameters, provides operation protection for compressor.
