Tension wire sensor

The Nemtek Tension Wire Sensor measures tension changes on the fence wire in a particular direction and will set off an alarm if there is a threat of intrusion.

The tension wire sensors will set off an alarm if the wires are cut or if there is an attempt to part the wires in order to gain entry. Each sensor is placed in the middle of a straight run and can detect up to a 100m span of wires. The tension wire system can be combined with an electric fence system. The combination of tension wires and a monitored electric fencing system creates a formidable detection and deterring barrier.
