由于对油压式活塞压力计(以下简称压力计)的使用与维护不够得当,至使故障常出,影响精度。本文就压力计的正确使用与维护介绍如下,供参考。 一、压力计的使用 1.当选用压力计进行高精度的压力测量时,只要精度能满足测量精度的要求即可。当用作检定压力仪表的标准器时,压力计的综 Due to the hydraulic piston pressure gauge (hereinafter referred to as pressure gauge) the use and maintenance is not properly enough to make the fault often out, affect the accuracy. This article on the correct use of pressure gauge and maintenance introduced below, for reference. First, the use of pressure gauge 1 elected to use pressure gauge for high-precision pressure measurement, as long as the accuracy can meet the requirements of measurement accuracy. When used as a gauge to check the pressure gauge, the pressure gauge ensemble
