Abstract
A taut wire fence system comprising a plurality of lenghts of taut wire strung in generally parallel orientation and mounted between a pair of anchoring posts and a sensor post, and characterized in that at least two of the plurality of lengths are interconnected whereby a change in tension on one of the lengths causes a change in tension on another one of the lengths interconnected therewith.
Claims9
A taut wire fence system comprising:
- a plurality of lengths of taut non-electrified wire strung in generally parallel orientation and mounted between a pair of anchoring posts, a least two of said plurality of lengths forming a set being interconnected mechanically on at least one anchoring post of said pair of anchoring posts, with multiple interconnected sets being provided, and
- sensor means mounted on a sensor post, said sensor means comprising a plurality of sensors each being adapted to interact with a different one of said lengths in said multiple interconnected sets so as to provide an indication of changes in tension therein,
- said mechanical interconnection in each of said multiple interconnected sets enabling a single disturbance producing a change in tension in one of said lengths to cause a corresponding change in tension in at least another one of said lengths, said changes in tension mechanically actuating a plurality of said sensors to provide said indication of changes in tension in at least two of said lengths of taut wire.
