摘　　要：压力控制器是工业过程测量与控制系统压力的一种专用仪表。其原理是当输入压力达到设定值时即可对预置压力进行控制或报警。本文通过对压力控制器测得值的不确定度进行分析,提高了压力控制器测得值的可靠性,为压力控制器的实际应用提供了参考。Pressure controller is a special instrument for measuring and controlling pressure in industrial process.The principle is that the preset pressure can be controlled or alarmed when the input pressure reaches the set value.In this paper,the uncertainty of the pressure controller measurement results was analyzed,which improves the reliability of the pressure controller measurement results,and provides a reference for the practical application of the pressure controller.
