Dual Action Tension Sensor (DATS2)

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. There are two models available to cater for different wire types; the TS-DATS2/XL is used with the galvanised and aluminium fence wires and the TS-DATS2/SS for the stainless steel wires. Detection range (straight line) up to 50m.
