Preformed Inductive Loops | Technical Specifications




CG16MMA

ASPHALT PAVE OVER PREFORMED INDUCTIVE LOOP

FUNCTION: Traffic Detection

SPECIFICATIONS:

Conduit:

  • Highly abrasion-resistant Polyurethane cover
  • High tensile strength braided synthetic fiber reinforcement
  • Excellent flexibility over a wide temperature range
  • Minimum pressure of 9,000 psi (62,050kPa)
  • Polyester core tube
  • Max. o.d. of 5/8" (16 millimeter)
cg16mma
Connection: Loop head to loop lead-in High tensile strength Polyvinyl carbonated "T" connector to connect the loop head to the protected lead-in

Wire:

  • Loop wire is 16 gauge tffn/thhn stranded single conductor
  • Number of wire turns to be determined by engineer or factory and will depend on, loop size, loop depth and site-specific requirements
  • Lead-in wires are machine twisted at a minimum of 4 twists per foot (30 cm)
  • One continuous wire is used in order to manufacture the loop and lead-in, no splices are used

Miscellaneous:

ENTIRE loop AND lead is filled with a flexible rubber asphalt emulsion to:
  • Prevent moisture from entering the conduit
  • Prevent false calls due to movement of the wire within the conduit
  • Protect the wire from pavement movement and stress, thereby dramatically increasing the longevity of the loop
