Abstract
:The paper describes the working principle and structure of a newly designed high-precision (micro-gal) gravimeter, which is basically a vertically suspending spring-weight system, using a highly sensitive capacitance sensor of movement in a controlled temperature environment in a borehole and a multi-frequency output for both earth-tide and earthquake monitoring. The preliminary test indicated that, while in a stabilization process, it had met all the technical requirements for a relative gravimeter used for earth tide and earthquake monitoring.
