活塞式压力计检定方法分析

The analyze of piston pressure gauges verification method

在常用的压力计量范围内,活塞式压力计是目前最理想的压力计量仪器。由于其具有准确度高、性能稳定、测量范围广、使用方便等优点,使其在压力计量技术中占有重要的地位。本文对活塞式压力计检定过程中的直接平衡法和起始平衡法进行了详细的介绍,对影响检定过程的各个因素进行分析,对比说明两种方法的优缺点。

In common pressure measure range, the piston pressure gauge is the most perfect instrument. Due to the high veracity, stability, large measure range, simple operation, make the most important status in the pressure measure. Here we particularly explain the direct balance method and the initiatory balance method, and analyze all kinds of factors effect, and show the contrast.
