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.
