石油工业部物探局仪器厂研制的 SD-Ⅱ型大地电磁测深仪是采用微机控制的电磁测深数据采集和回放监视系统。它由磁(电)场接收器、采集部件、微机记录器、磁带机、精密信号发生器、六笔笔录仪以及发电机等部件组成,并配有功能较齐全的野外操作程序和系统诊断程序,是记录大地电磁场变化信息的物探专用仪器。样机经过野外试验、性能对比(与国外生产的同类型仪器)及试生产性考核,已具备鉴定条件。为此,
Geophysical Bureau Bureau of Petroleum Industry Instrument Factory developed SD-Ⅱ-type electromagnetic sounder is the use of computer-controlled electromagnetic sounding data acquisition and playback monitoring system. It consists of magnetic field receivers, acquisition units, computer recorders, tape drives, precision signal generator, six pen recorders and generators and other components, and is equipped with more complete field operations and system diagnostic procedures , Is a geophysical instrument dedicated to record changes in the electromagnetic field of the earth. Prototype after field tests, performance comparison (with the same type of equipment produced abroad) and test production test, already have the identification conditions. to this end,
