Inductive loops may be used alone, or can be incorporated with other traffic systems to provide information regarding vehicle presence. A loop is a wire wrapped around and around to form an inductor. The loop's inductance changes and produces a readable signal when a vehicle passes over it.
IRD carries permanent loops of any dimension for permanent epoxy road installations and temporary loops that are secured to the road surface with adhesive tape. We also have pre-assembled quick stick loops for fast, easy temporary installation as well as preformed pave over loops.
Used to create temporary loops that are secured onto the road surface with adhesive tape. The lead wire is first wrapped around road nails that have been driven into the pavement, and then taped to the road surface. The road nails are removed once the loop is secured with the road tape.
Used for easy installation of temporary loops. These loops come pre-assembled; you only need to clean the area, remove the adhesive backing, and stick the loop to the road surface. It has an 18" (54.9 cm) lead wire stub using a 2 pole connector. Lead wire from the counter or other electronics can be attached to the lead stub, and when you are finished with the loop simply unplug the 2 pole connector.
