System and method for batch metering and verification of precision pressure gauge

Abstract

The present invention relates to a system and a method for batch metering and verification of a precision pressure gauge. The system comprises a prepressing device, a medium container, a digital precision pressure gauge, a prepressing hand pump, a plurality of stop valves, a plurality of verified precision pressure gauge joints, a plurality of first single-gauge fine adjustment hand pumps and a plurality of second single-gauge fine adjustment hand pumps which are connected with a pressure pipeline. The system further comprises a control system and collection keys. Each verified precision pressure gauge joint corresponds to one set of stop valves, one first single-gauge fine adjustment hand pump, one collection key and one second single-gauge fine adjustment hand pump; and the control system comprises a control unit, a signal input unit, a data collection unit and a data processing unit. The problems are solved that a current pressure gauge is low in metering and verification efficiency, cannot achieve digitization, intelligence and batch, and is large in error introduction probability, and the problem is eliminated that a current verification method is actively interposed by people.

Description

technical field [0001] The invention belongs to the field of measurement verification, and in particular relates to a precision pressure gauge batch measurement verification system and method. Background technique [0002] The existing measurement and verification method for precision pressure gauges is to fill in the information of a single precision pressure gauge to be tested in the original paper record, calculate and fill in the maximum allowable error and maximum allowable return error of the precision pressure gauge to be tested; fill in the standard device (including Piston pressure gauge, digital precision pressure gauge, pressure controller, etc.) relevant information into the original paper records; a single precision pressure gauge to be tested is effectively connected to the standard device, and the pressure of the standard device is loaded to each verification point respectively. Estimate and read the checked watch according to one-tenth of its graduation value...
