Fujian Metrology Institute 2MN static weight / superimposed composite force standard device application
[ China Instrument Network Instrument Development] Recently, the 2MN static weight/superimposed composite force standard device developed by Fujian Metrology Institute successfully completed the installation and commissioning, and was put into use after being calibrated by the China Test Institute. At the request of a sensor company in Fujian, the standard device was first calibrated for the 2MN force sensor on December 27, 2018. This signifies that the device is officially put into practical use and will trace the source of high-precision metrics in China. The problem provides solid and reliable technical support.
Carry out calibration services
The standard device is the research result of the original 2ND static weight/superimposed composite force standard device of the former AQSIQ science and technology project led by the Metrology Institute of Fujian Province. Its overall technical plan was independently designed and developed by the institute. The project broke through the key technologies such as the codeless exchange technology in the loading and unloading process, the barrier-free disassembly and assembly technology, and the whole positioning technology of the weight. It solved many technical problems of the previous heavy machine and obtained 7 patents and was built. At present, the first static and heavy force standard device with the largest range and the most advanced technology level in China has an accuracy of better than 0.005%.
The successful development of the device solves the problem that China's 1MN force value cannot be calibrated with high accuracy, greatly improves the level of China's high-powered mass transfer system, effectively serves domestic high-end sensor research and development, and will be China's aerospace, defense and advanced manufacturing. The industry provides strong technical support.
