金属箔式应变片是应变敏感元件，通过它转换被测部位受力状态变化，电桥完成电阻到电压的比例变化。
Metal foil strain wafer is a live strain component, through which the variation of lading condition is shifted. The resistance module can vary from resistance to voltage in proportion.
利用电阻应变片、动态压力传感器、滑环式引电器和磁带记录仪等，录取叶片振动应变和动叶出口压力信号，然后回放磁带，做信号处理。
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.
电阻应变片有粘贴式和非粘贴式两种基本形式。
Two basic forms of the resistance strain gage are the bounded and the unbounded types.
