Vehicle 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.

Vehicle loop detector wiring diagram.

Having a car pass several inches on top of it produces such an. 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. Safety loops are used to prevent a gate from closing on a vehicle. 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.

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 is connected to the detector. Find emx d tek loop detector here.

The wire gauge is not critical to proper operation of the loop detector. 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. When a vehicle enters the loop the frequency increases causing the detector to send an output to the gate operator. A wiring diagram is a streamlined conventional pictorial representation of an electrical circuit.

The loop then tunes to a resonate frequency and the detector constantly monitors the frequency for changes. 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. Two loops can be wired to one detector. The size of the loop depends on the job conditions.

Exit loops are used to open gates to allow a vehicle s exit. 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. It reveals the parts of the circuit as simplified forms as well as the power and signal connections in between the devices. The wire should maintain its integrity under the pavement stress.
