摘要

本文设计了一种多通道的压力传感器标定系统。它由数字万用表(DMM)、高性能压力发生器、数字压力校准器和计算机组成。几乎可以同时校准10个压力传感器。本系统的上层软件采用LabVIEW2014编程，实现了数据采集、信息处理、误差计算和报表生成四大功能。利用该系统对传感器进行了标定，验证了该系统的精度。实验结果表明，所设计的校准系统的压力测量范围为0 ~ 60MPa，压力精度等级优于0.05%F·S，压力波动率优于0.01%F·S。结果表明，该多通道校准系统能够满足压力传感器校准的精度要求。

Multi-channel automatic calibration system of pressure sensor

A multi-channel calibration system is designed to calibrate the pressure sensor in this paper. It composes of digital multimeter (DMM), high performance pressure generator, digital pressure calibrator and computer. Almost 10 pressure sensors can be calibrated at the same time. The upper software of this system is programmed by LabVIEW2014, which has four functions: data acquisition, information processing, error calculation and report generation. A sensor is calibrated by this system to validate the accuracy of this system. The experimental result shows that the pressure measuring range of the designed calibration system is 0 to 60MPa, the pressure accuracy class and the pressure fluctuation rate are superior to 0.05%F·S and 0.01%F·S respectively. It indicates that this multi-channel calibration system can meet the accuracy requirements of pressure sensor calibration.
