Pressure gauge batch metering and verifying system and method

Abstract

The present invention relates to a pressure gauge batch metering and verifying system and method. The pressure gauge batch metering and verifying system comprises a pre-pressing device, a medium container, a digital precise pressure gauge, a pre-pressing hand pump, a plurality of first stop valves, a plurality of second stop valves, a plurality of verified gauge joints, a plurality of single gaugefine tuning hand pump, a control system and an acquiring key which are connected in a pressure pipeline. A control unit is connected with the pre-pressing device, an information recording unit is used to record the information of the verified gauges and the digital precise pressure gauge and divide the verification points of the verified gauges automatically according to the information of the verified gauges, and a data acquisition unit is connected with the digital precise pressure gauge via the acquiring key and is used to acquire the real-time pressure data information of the digital precise pressure gauge, and a data processing unit is used to analyze and process the data information acquired by the data acquisition unit. According to the present invention, the problems that the conventional pressure gauge metering and verification efficiency is low, the digital, intelligent and batch pressure gauge metering and verification cannot be realized, an error introducing probability islarge, etc., are solved, and the problem that people actively intervene a conventional verification method is eliminated.

Description

technical field [0001] The invention belongs to the field of measurement verification, and in particular relates to a batch measurement verification system and method for pressure gauges. Background technique [0002] The existing pressure gauge measurement and verification method is to fill in the information of a single tested pressure gauge in the original paper record, calculate and fill in the maximum allowable error and maximum allowable return error of the tested precision pressure gauge; fill in the standard device (including piston type) pressure gauge, digital precision pressure gauge, pressure controller, etc.) related information into the original paper records; a single 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, and the tested The watch is estimated and read according to one-fifth of its graduation value, and each point is read twice befor...
