| Abstract: | The design idea,the overall structure and the principle of operation of main components of extensometer of USBE-1type 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. |
