Using resistance strain gage, dynamic pressure sensor, slip ring and tape recorder, the blade vibration strain and exit pressure signals of rotor blades are recorded and then processed.
It can solve the difficulty of low insulation resistance of high temperature strain gage adhesives and can raise the accuracy of high temperature strain measurements.
这种方法可以解决无机应变胶高温绝缘电阻过低的问题，并可以提高高温应变测量的精度。
