Borehole tilt meter

摘要

A devised tilt meter detects tilt of the receptacle installed in the ground and/or in the solid construction, to detect the displacement of a pendulum suspended by thin metal springs. A cavity exists near the middle of the receptacle with a pendulum, the springs, a detector along the lateral side of the receptacle of the tilt meter. Wires for signal and power lines of other tilt meter are easily passed through this cavity. This mechanism with a cavity near the middle of the receptacle is very useful for an array observation of tilt in the ground and/or in a solid construction.
