A tension sensor for an electrified fence which includes two contacts and a spring arrangement which, in response to a tension level in a taut wire in the electrified fence keeps the contacts electrically connected to each other when the tension level is below a predetermined value and which breaks such electrical connectivity when the tension level exceeds the predetermined value.
G01L 5/103 - Apparatus for, or methods of, measuring force, work, mechanical power, or torque, specially adapted for specific purposes for measuring tension in flexible members, e.g. ropes, cables, wires, threads, belts or bands using electrical means using sensors fixed at one end of the flexible member
