摘要A semi-automatic verification device for pressure gauge is studied in this paper. Its medium is compressed air, which is operated by a Pressure Regulators to control the fast lifting and lowering pressure tester and software system. The verification efficiency is superior to manual and automatic verification system. This system is divided into two parts: hardware device and software system. The hardware includes computers, printers, air compressors, gas reducers, fine-tuning valves, connecting pipes and several standard interfaces and standards measurement. The software part is composed of data entry, preservation system, certificate generation and printing system.
