影响弹性元件式压力表计量性能的因素分析

Analysis of Factors Affecting the Measurement Performance of Elastic Element Type Pressure Gauge

弹性元件式压力表在计量显示和压力控制中具有一定的优势,是常见的压力计量器具,在各行各业的计量工作中作出了巨大贡献。然而,弹性元件式压力表计量性能也会受到一些因素的影响。通过介绍弹性元件式压力表计量检测内容和性能要求,找出了回程误差、示值误差和轻敲位移是对压力表计量性能影响最大的因素,并分析了其产生的原因。

The elastic element type pressure gauge has certain advantages in the measurement and pressure control, it is a common pressure measurement apparatus, and has made a great contribution in the measurement work of all walks of life. However, the measurement performance of the elastic element type pressure gauge is also influenced by some factors. Through the elastic element type pressure gauge measuring content and performance requirements, the author finds out the return error, showing the value of error and tapping displacement is the metrological performance of the factors having the greatest effect on the pressure surface, and analyzes its reason.
