ã€Instrument Development of China Instrument Network】 In July 2016, the Institute of Science and Technology Planning Project “Development of Portable Air Barometer Test Device†(Project Number: GOORY1403) undertaken by the Shanghai Institute of Metrology and Measurement Technology Online passed the acceptance of experts. .
The empty box barometer is an atmospheric pressure measuring instrument that is based on deformation elements. It is widely used in meteorology, military, aeronautics, navigation, agriculture, surveying, geology, industrial and mining enterprises, scientific research, etc. The on-site measurement business demand is very low. However, the existing metrological verification devices are too large to handle and cannot meet business needs.
The core of the project “Development of portable air box pressure gauge verification device†is to develop a function-integrated mainframe, and based on the good sealing performance of the box, processing a moderate-sized and transparent inspection box. This project adopts a built-in high-precision absolute pressure pressure module with an accuracy of 0.01, which not only satisfies the measurement requirements of all empty box pressure gauges and empty box barometers, but also satisfies the mathematical barometer below 0.02 level or pressure transmission. Measuring requirements for pressure sensors. In addition, while meeting the metering requirements of the empty box barometer, the design emphasizes the importance of being portable, achieving the features of small size, light weight, and full functionality. The core of the device is a host that integrates a built-in pressure source, power supply, control system, humanized display system, and external system. The multi-functional and integrated design meets the requirements for convenient and quick installation. The whole set of verification devices adopts a reverse-stitching method to solve the problem of sealability of the box, and a transparent toughened glass is used as the sealing cover at the top to make the sealing box and sealability of the device's verification box a requirement.
The portable air box pressure gauge verification device has been widely applied in meteorology, chemical industry, environment and other fields. It has passed the review of new projects, and it has also been listed in the 2017 New Bureau Project, which provides a theoretical basis and technology for related business development. support.
