摘要
针对0.02级大气数据测控仪的校准需求,设计了一种基于全自动气体活塞式压力计的压力补偿装置,克服了传统活塞式压力计输出局限于定点值的问题,实现了压力的连续可调输出。通过构建完整的校准装置测量模型,运用GUM法对测量不确定度进行了评定。经过理论计算与实验验证,测量模型的理论计算值与实际测量值之间偏差小于0.001%,验证了模型的准确性。最后,通过传递比较法验证了计量标准性能,确认了整套校准装置的不确定度满足量值传递要求,适用于0.02级大气数据测控仪的校准工作。
A pressure compensation device based on a fully automatic gas piston pressure gauge was designed and implemented to meet the calibration requirements of 0.02-grade air data test set.The problem of traditional piston pressure gauge output being limited to fixed-point values was overcome,and continuous adjustable pressure output was achieved.The measurement uncertainty was evaluated using the GUM method by constructing a complete calibration device measurement model.After theoretical calculation and experimental verification,the deviation between the theoretical calculation value and the actual measurement value of the measurement model was less than 0.001%,which verified the accuracy of the model.Finally,the performance of the measurement standard was verified through the transfer comparison method,confirming that the uncertainty of the entire calibration device met the requirements for dissemination of the value of a quantity and was suitable for calibration of 0.02-grade air data test set.
