Motion29's factory manufactured preassembled loop has a circumference of 6 metres and a connection tail of 15 metres. The loop is designed to be used as a 2 metre width across the road with a minimum of 1 metre section in the direction of travel. The edge of the loop should be around 0.35 and 0.5m from the edge of the roadway.
The inductance of this installed loop will be around mid-point of a ProLoop2 inductive loop controller to give you optimal performance.
When the slot in the roadway is prepared, it should be around 50mm deep and free from any debris that could damage the cable. The corners should be chamfered by 45º to ensure the cable has a smooth path and not forced into a 90º bend. The slot should then be filled with a sealing compound to weatherproof the loop ensuring that the loop is protected from hot materials such as bitumen. Epoxy resins are ideal as they hold the loop firmly without any significant heat generated during installation.
Custom loops can be produced on request.
