Development of special measuring tool for trace of micro force value
AbstractThis paper introduces the development of the special traceability measuring tool for microforce value with the test force range of 0.009807 N ~ 9.807 N (1 gf ~ 1 kgf) and the accuracy of better than ± 0.1 %, including the selection of the electromagnetic balance module, the design of the hardware structure, and the compilation of the software program. Finally, the special traceability measuring tool integrating the test measurement, automatic data collection and automatic data processing is realized, and the test verification result is given. It provides a method to solve the problem of trace the small force value of existing micro Vickers hardness tester and Knoop hardness tester.
