Tension Sensor Systems

Tension Sensor Systems

The Nemtek taut wire system measures tension changes in a particular direction on an electrified or non electrified fence, and 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. The combination of a taut wire and monitored electric fencing system provides a high level of security, from both a detection and a deterrent angle.

Nemtek Dual Action Tension Sensor 8kg Set (N.TS-DATS2)

Nemtek Dual Action Tension Sensor 8kg Set

PRODUCT DETAILS

The patented Nemtek Dual Action Tension Sensor – DATS2 can detect a change of tension in the fence wire. It uses the electric-fence monitoring circuit to create an alarm condition on the energizer. The dual action increases the likelihood of an intruder being detected and reduces the possibility of tampering. The DATS2 can accommodate galvanised steel, stainless steel, and aluminium wires with a diameter range from 1.0mm – 1.6mm. Detection range (straight line) Up to 50m

Features
• The DATS2 is paired up with the Heavy-Duty Compression Spring Hybrid (ES-CNT2HB). This is so that the tension in the fence wires can be adequately maintained
• DATS2 will detect a change in tension on a fence line
• DATS2 can detect an open circuit at its first-stage trigger
• It can detect a dead short at its second-stage trigger
• Constructed from robust material to suit all wire types up to 1.6mm
• Easy to install and retrofit onto most existing Nemtek electric fences
