动态压力传感器 [自] dynamic pressure sensor
- 利用动态压力传感器,测定了颗粒床颗粒间挤压应力与撞击速度之间的关系;
The relation between inter-granular stress and impact velocity were measured by using dynamic pressure transducer. - 研究了连接动态压力传感器的信号线长度、放大器的滤波频率和数据采集系统的采样频率对空气压力波测量的影响。
The effects of the signal line length, the filter and the sampling frequencies on measuring air pressure pulse were studied in this paper. - 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.
