摘要
本文针对压力传感器动态校准需求,提出了一种基于虚拟仪器的正弦动态压力校准方法,设计了正弦动态压力校准系统,分别从总体设计方案、硬件配置及软件控制三方面进行介绍,然后对正弦动态压力校准系统进行试验及不确定度评定,结果表明该方法可行有效,可满足航空航天、工业领域中对压力动态测量要求。
According to the dynamic calibration needs of pressure transducer,a method of sinusoidal dynamic pressure calibration based on virtual instrument is proposed. The system of sinusoidal dynamic pressure calibration based on Labview is designed in this paper,including overall design schemes,hardware configuration and software control. This paper also performs a test on the system of sinusoidal dynamic pressure and gives the uncertainty evaluation. The result shows that the method is feasible and effective and it meets the need of dynamic pressure measurement in aerospace and industrial areas.
