一、概述近十年来,由于科学技术的发展,因此,对压力检测仪表的精度,稳定性,及可靠性等指标都提出了更高的要求。在工业现场流程的设备管道上,或在仪表控制室内,作为仪表巡检工人来说,最关心的是在运行中的检测仪表的灵敏度和精度的可靠性。为此须经常把现场管道上和控制室内的仪表拆下来送到试验室内进行校验。这样既浪费时间又易损坏仪表。为解决这一问题,一些工
First, an overview Over the past decade, due to the development of science and technology, therefore, the pressure detection instrumentation accuracy, stability, and reliability indicators have put forward higher requirements. In the field of industrial equipment pipeline process, or in the instrumentation control room, as instrumentation patrol workers, the most concerned about the sensitivity of the instrumentation in operation and the reliability of accuracy. For this purpose, the instruments on the pipeline and control room must be removed and sent to the laboratory for verification. This is a waste of time and easy to damage the instrument. To solve this problem, some workers
