INDUCTIVE LOOP DETECTOR CABLES
Inductive loop cable is used to measure and control traffic flow. The cables are buried beneath the road in ‘loops’ and an electrical current is passed through them creating a magnetic inductive field. It is the vehicle passing through this field that creates a disturbance and a means by which to measure traffic flow and vehicle type. Typical applications are for traffic control signals, safety cameras, variable speed control systems, flow monitoring and access control. The cables have to be of a robust design to withstand a hostile working environment and accommodate back filling with hot bitumen.
