本文阐述了FSQ型浮子水管倾斜仪的设计思想及仪器的基本原理。着重介绍了仪器特点及试验效果。 FSQ型浮子水管倾斜仪实现了遥测自动记录,具有灵敏度高、稳定性好、大的动态量程,简易、可靠的标定装置及结构简单、操作、维护方便等特点。文章以室内、台站试验数据说明仪器设计原理正确、性能稳定、可靠,可以满足连续可靠地记录地壳长期倾斜变化及其固体潮观测的需要。 This article elaborates the design idea of ​​FSQ float tube tiltmeter and the basic principle of the instrument. The characteristics and test results of the instrument are introduced emphatically. FSQ-type float pipe tilt meter to achieve the automatic telemetry records, with high sensitivity, good stability, large dynamic range, simple, reliable calibration device and simple structure, operation, easy maintenance and so on. The article, based on indoor and station test data, shows that the principle of instrument design is correct and its performance is stable and reliable. It can meet the needs of continuously and reliably recording the long-term tilt change of the crust and its solid tide observation.
