Title: Simplified ground displacement gauge by variable voltage divider
Inventor: SHOJI MIKIO
IPC: G01L5/00
Filed: 1988-03-28
Abstract: PURPOSE:To detect the displacement of the ground without exerting a fault on the execution by extending an providing a wire between two points of the ground by a constant-load spring, coupling a variable voltage divider to the constant-load spring and generating an output corresponding to the displacement of the ground between two points. CONSTITUTION:A constant-load spring 9 holds a wire 3 under tension by a constant-load. That is, when an elongation has been generated in an interval L between two points A, B of the ground, the spring 9 feeds out or draws in the wire 3 by a displacement of a rotation, etc., and holds the wire 3 in a tension state under the constant-load. In this case, since the wire 3 held in the constant-load does not expand nor contract, the feed-out or draw-in quantity of the wire 3 shows the expansion and contraction quantity of the interval L between two points A, B of the ground, namely, magnitude of the displacement of the ground. Also, a variable voltage divider which has been coupled to the spring 9 can generate an output corresponding to the displacement of the rotation, etc., of the spring 9, therefore, the displacement of the ground between two points A, B can be shown by this output.
