Loop detector the loop detector is the electronic component that controls the loop system.
Vehicle loop detector wiring diagram.
The loop then tunes to a resonate frequency and the detector constantly monitors the frequency for changes.
Inductance loops are available as direct burial or cut in.
See installation diagram loop detectors are used to detect the presence of vehicles.
The detector powers the loop causing a magnetic field around the wire.
As you may have guessed this kind of detector works by detecting an inductance change in a wire loop aka coil buried in the road.
The wire gauge is not critical to proper operation of the loop detector.
Since asphalt is more flexible than concrete it is recommended that a heavier gauge wire be used for loop installations in asphalt.

Having a car pass several inches on top of it produces such an.
When a vehicle enters the loop the frequency increases causing the detector to send an output to the gate operator.
In general direct burial loops are placed below the surface prior to application of asphalt or concrete while cut in loops are installed within a slot sawed into.
The wire should maintain its integrity under the pavement stress.
The loop is connected to the detector.
A wiring diagram is a streamlined conventional pictorial representation of an electrical circuit.
The size of the loop depends on the job conditions.
A preformed loop is typically 3 to 5 turns of loop wire encased in pvc pipe for use in new construction before the pavement is installed.
Two loops can be wired to one detector.
Assortment of loop detector wiring diagram.
It reveals the parts of the circuit as simplified forms as well as the power and signal connections in between the devices.
These detector boards have.
This video just want to show our traffic vehicle detector function and the loop inductive can be identification if you want to use it for traffic control app.
Find emx d tek loop detector here.
The loop wire is encased in pvc pipe to hold the loop s shape and to protect the loop wire from damage while the pavement is installed.
Safety loops are used to prevent a gate from closing on a vehicle.
