Permanent Inductive Loops
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.
Model 8050 Permanent Loop Kit
Used to create loops of various dimensions for installation with epoxy in paved roads. The loop wire and lead-in cables are placed into saw-cuts in the roadway. Loop Sealant is used to secure the loop wire into the roadway. Permanent inductive loops are designed for use in Asphalt Concrete (A/C) or Portland Cement Concrete (PC/C) roadways with a pavement thickness of 4" (10 cm) or greater.
Comes with:
- 200 feet (61 m) of 14 AWG loop wire
- 200 feet (61 m) of 18 AWG lead in wire
- Splicing material
- 7 tubes of loop sealant
Preformed Loop
Can be paved over for installation in new roads. The preformed loop consists of an insulated loop wire set inside a non-metallic flexible conduit with a water tight, sealed lead-in connection. It can be set in place for new paving, concrete pours, gravel roadways and brick pavers.
Comes with:
- Over 25 standard loop sizes available from 2' x 6' to 6' x 30' (0.6 m x 1.8 m to 1.8 m x 9.1 m)
- 16 or 18 AWG loop wire
- Standard lead lengths available from 20' to 100' (6.1 m to 30.5 m)
- 16 or 18 AWG lead in wire
