一、引言在测量某空间的气体或液体静压力时,除近代迅速发展的小型压力传感器,常把测压敏感元件直接置于被测压力空间外,多数情况是通过引压导管内的气体或液体(即引压介质),把被测空间的气体或液体压力(有时用敏感膜片与被测空间隔离),引入测压仪表,进行测量。这时仪表指示的压力,只是引入仪表的某特定部位的压力。特定部位与被测空间往往存在高度差,因而指示压力与被测空间压力不同。要得到正确的被测值,就需要进行引压介质的高度修正。这个问题对使用液体引压介质的测量者,无疑都会考虑并加以修正。但是,
I. INTRODUCTION In measuring the static pressure of a gas or liquid in a space, in addition to the rapid development of modern small pressure sensors, often the pressure sensing element placed directly outside the measured pressure space, in most cases by the pressure of catheter gas or Liquid (ie pressure medium), the measured space gas or liquid pressure (sometimes with a sensitive diaphragm and the space under test isolation), into the pressure gauge, the measurement. At this time, the pressure indicated by the meter is only the pressure introduced into a specific part of the meter. There is often a height difference between a specific part and the measured space, so the indicated pressure is different from the measured space pressure. To get the correct measured value, you need to re-pressure the height of the media correction. This issue is undoubtedly considered and corrected for the surveyor using liquid pressure media. but,
