Vehicle Loop Detector Wiring Diagram
The wire gauge is not critical to proper operation of the loop detector.
Vehicle loop detector wiring diagram. Exit loops are used to open gates to allow a vehicle s exit. A wiring diagram is a streamlined conventional pictorial representation of an electrical circuit. The wire should maintain its integrity under the pavement stress. 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.
Safety loops are used to prevent a gate from closing on a vehicle. When a vehicle enters the loop the frequency increases causing the detector to send an output to the gate operator. Inductance loops are available as direct burial or cut in. 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.
These detector boards have. See installation diagram loop detectors are used to detect the presence of vehicles. Find emx d tek loop detector here. Loop detector the loop detector is the electronic component that controls the loop system.
Two loops can be wired to one detector. Having a car pass several inches on top of it produces such an. Since asphalt is more flexible than concrete it is recommended that a heavier gauge wire be used for loop installations in asphalt. The detector powers the loop causing a magnetic field around the wire.
The loop then tunes to a resonate frequency and the detector constantly monitors the frequency for changes. The loop is connected to the detector. The size of the loop depends on the job conditions. 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.
Doorking offers loop detectors models 9409 9410 and 9411 that plug directly into the gate operator control board eliminating the wire harness and wiring connections other than the loop lead in wires. 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. 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. Assortment of loop detector wiring diagram.
