摘要
压力受感器自动校准及数据处理系统是为航空发动机精确压力测试而建立的。该系统以高精度的振动筒压力传感器为主体,自行研制高精度多通道频率测量仪,并配以14位A/D卡,由计算机自动控制三自由度坐标架机构移动探针进行校准,经数据处理后输出校准曲线。该系统具有精度高、自动化程度好、使用方便的特点,有效地辅助了探针气动设计。
Pressure probe automatic calibration and data process system was built for high precision pressure measurements on aero-engine. This system includes high precision vibrating cylinder transducers, 8-channel frequency measuring instrument, advantech PCL-814 DAS card, ROTADATA 3-axes actuator system for probe traversing . All these components are automatically controlled by personal computer,through data processing, the printer plots the calibration curves. This system takes advantages of high precision, well automation, convenient user interface, aids the probe aerodynamic designing effectively.
