Abstract

The invention belongs to the field of instrument verification and relates to a verification method and a verification system of pressure gauges. According to the verification method of the pressure gauges provided by one embodiment of the invention, the loading and unloading of the pressure gauges can be automatic by controlling the pressure gauges to be transmitted in specific postures, the improvement of the automation degree of the pressure gauges can be facilitated; when errors of the pressure gauges are obtained, vibration is used for replacing manual tapping operation, the multiple pressure gauges can be calibrated at the same time, and the calibration efficiency is improved. The calibration system of the pressure gauges is provided to achieve the calibration method and improve the automation degree of the calibration of the pressure gauges.

Description

technical field [0001] The invention relates to the field of instrument verification, in particular to a verification method and a verification system of a pressure gauge. Background technique [0002] In the current field of instrumentation verification, fully independent pressure gauge verification equipment has not yet matured, which is mainly limited by the diverse specifications of pressure gauge dimensions, joint sizes, ranges, etc., as well as complex and cumbersome verification processes and Multiple standard test methods. The traditional mechanical pressure gauge verification is to manually turn the movable nut by the verifier, fix the pressure gauge to the output port of the pressure source, and then pressurize in sections, tap the case, read the pointer indication, record the indication and The process of unloading the pressure gauge is cumbersome and highly dependent on manual experience, resulting in low efficiency of pressure gauge verification, and the accura...
