以3種常見之市售磁環感測器(磁簧開關型)進行附量尺拉伸變形(彈性變形)

以3種常見之市售磁環感測器(磁簧開關型)進行附量尺拉伸變形(彈性變形)與水浮力效應對地陷監測井量測作業影響檢驗，檢驗結果顯示，磁環感測器隨附量尺之彈性變形與浮力效應對磁環位置量測精度及環間距量影響不顯著，惟若隨附量尺有產生塑性變形情形，則將影響量測精度。

To 3 species common of city sale magnetic ring sensor (magnetic spring switch type) for attached volume feet stretch deformation (elastic deformation) and water buoyancy effect on sinkholes monitoring well volume measuring job effect test, test results displayed, magnetic ring sensor with attached volume feet of elastic deformation and buoyancy effect on magnetic ring location volume measuring precision and the ring spacing volume effect not significantly, only if with attached volume feet has produced plastic deformation case, is will effect volume measuring precision.

3 common to the commercially available magnetic sensor (reed switch type) were attached ruler tensile deformation (elastic deformation) and the buoyancy effect of water monitoring wells subsidence measurements job impact test, test results show that the magnetic ring elastic deformation and buoyancy effect of magnetic position sensor comes with dipstick measurement accuracy and the amount of space on the ring is not significant, but if the supplied ruler has plastically deformed situation, it will affect the measurement accuracy.

In 3 kinds of commercially available magnetic sensor (magnetic reed switch type) were attached scale tensile deformation (elastic deformation) and water buoyancy effect on the ground subsidence monitoring wells measurement impact test, test results show that the magnetic sensing sensor with elastic deformation scale and buoyancy effect on magnetic position measurement accuracy and influence of ring spacing was not obvious, but if the attached ruler"s plastic deformation, it will affect the accuracy of measurement.
