摘要
介绍USBE-1型超短基线伸缩仪总体设计思想、整体结构和主要部件的工作原理及台站试验情况。试验结果表明,由于开发了密封结构的高精度电容微位移传感器,缩短了仪器基线长度,在不大于1 m条件下也能记录到清晰的应变固体潮汐,满足了较小的工作空间及地震应急监测等需要。
The design idea, the overall structure and the principle of operation of main components of extensometer of USBE-1 type and the test at stations are introduced. Test results show that thanks to the development of a sealing structure of high-precision capacitance sensor for micro-displacement the length of instrument baseline can be shortened greatly for example, to not more than 1 m and it can record the clear response to the solid tides, so can meet the small space and requirement for earthquake emergency.
