国产高精度DI仪的研制进展
The development of high-precision DI instrument
摘要
Abstract
brief overview to the development process of the apparatus with high accuracy, including selecting material designing structure and detection circuit for the fluxgate sensor, which covers a core part in researching on the magnetic detection system. Furthermore, a high-precision optical theodolite using non-magnetic alloy with high hardness hardwearing non-magnetic ball and elastic non-magnetic steel is demagnetized. At last, tests about the magnetic detecting system non-magnetic theodolite and entire machine are performed, the results show that the performance index of DI instrument is superior to the domestic product, and up to international advanced level.关键词
