Vehicle Loop Detector Wiring Diagram

Vehicle loops and loop detectors are used to detect the presence of a vehicle to open a gate or as a safety device to prevent the gate from closing on a vehicle in its path.

Vehicle loop detector wiring diagram. 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. Assortment of loop detector wiring diagram. 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. 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.

The detector powers the loop causing a magnetic field around the wire. 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. Inductance loops are available as direct burial or cut in. 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.

The wire gauge is not critical to proper operation of the loop 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. 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 loop is connected to the detector. Safety loops are used to prevent a gate from closing on a vehicle. The wire should maintain its integrity under the pavement stress. Exit loops are used to open gates to allow a vehicle s exit.

The size of the loop depends on the job conditions. See installation diagram loop detectors are used to detect the presence of vehicles.

These detector boards have.

It reveals the parts of the circuit as simplified forms as well as the power and signal connections in between the devices. The loop then tunes to a resonate frequency and the detector constantly monitors the frequency for changes. Loop detector the loop detector is the electronic component that controls the loop system. Two loops can be wired to one detector.
