0.01级数字压力计标准装置(数字压力计)测量结果的不确定度分析

Uncertainty Analysis of the Measurement Results of the Standard Device(Digital Pressure Gauge) of 0.01-level Digital Pressure Gauge

0.05级及以下数字精密压力表广泛地应用于实验室,工业生产等场所的压力测量。目前0.05级的数字压力计多用0.02级活塞压力计进行检定。这里介绍的是基于新型的0.01级数字压力控制器为标准器进行检定的不确定度进行分析。

0.05-level and the following digital precision pressure gauges are widely used in the laboratory, industrial production and other places of pressure measurement. At present, the 0.05-level digital pressure gauge is usually tested by 0.02-stage piston pressure gauge. This paper introduces the uncertainty of the analysis based on the new type of 0.01-level digital pressure controller.
