Multi-Voltage Vehicle Detector makes it simple to manage your stock. You only need one detector in your stock room and on your truck. The JTLD-100 solves the problem of not knowing which voltage to take for service call or an installation. Reduce the costs of inventory by stocking only one loop detector - with universal voltage

Shenzhen Jutai loop detector prides itself on being the loop experts.Now we are better able to offer gate installers more in depth technical support. If the wires of the loop itself are twisted, will it have an effect on its ability to detect vehicles? That is what we set out to clarify with our new test. 
Purpose of the test: 1.Observe and record if twisted loop wire has any different detection than untwisted loop wire. 2.Dispel the myth that a twist in the loop wire will cancel the EMFs (Electromagnetic Fields) causing a reduction in loop detector performance. 
Conclusions:
1.There is no difference in detection strength between
twisted loop wire or untwisted loop wire.
2.There is no evidence that "canceling of the EMFs"
(Electromagnetic Fields) are taking place in loop
applications. Twisting of the loop wire itself has no
effect on detector performance.
3.Whether the loop wires are twisted or untwisted, the
EMF fields will be the same size as long as the wires
are held tightly together (jacketed or twisted).
4.Twisting the wires has little to no effect on a loops
EMF.
