SN358地震仪是美国Sercel公司研制的一种具有扩展能力的常规地震数据采集系统。它是一种组件式轻便型仪器,每一组件装置的最大重量不超过27公斤。用户可以根据观测系统的实际道数随时选用组件个数。全部组件具有良好的防水性能和足够的坚固性,可以在任何复杂的野外条件下工作。 SN358规范形式的记录范围从8道1/8ms采样直至132道2ms采样;扩展了的《MARINE》形式将具备254道2ms采样的记录能力,这时数据是以“多路”格式记录在磁带上的;SN358具备一整套全面的检测系统,仪器的所有模拟特性都可以在野外计算并显示在控制屏幕或线路打印机上。
The SN358 seismometer is a kind of extended capacity conventional seismic data acquisition system developed by Sercel Company of the United States. It is a modular portable instrument with a maximum weight of 27 kg per unit. Users can choose the number of components at any time according to the actual number of observation system. All components have good water resistance and rugged enough to work under any complex field conditions. The SN358 canonical record ranges from 8 1 / 8ms samples up to 132 2ms samples; the expanded “MARINE” format will have 254 2ms samples of recording capability when data is recorded on tape in “multiple” format ; The SN358 includes a comprehensive inspection system where all the simulation features of the instrument can be calculated and displayed on the control screen or on the line printer in the field.
