Preformed Inductive Loops | General Information





Patriot Detection provides products and services to companies around the world who seek to integrate the highest quality traffic detection components into their traffic systems. Loops manufactured for transportation use continue to provide Patriot Detection with growing markets and new opportunities for establishing successful business relationships with distributors in the United States and abroad.

Whether installation requires a cut-in, pave-over, or direct hot asphalt overlay, Patriot Detection preformed inductive loops (P-ILDs) are time-tested and warranted to last 15 years without failure. Patriot Detection not only guarantees the best product on the market, but also completes the customer experience with superior customer service.

Each order for Patriot Detection P-ILDs is custom-made and assembled in our factory for total customer satisfaction. Custom assembly not only avoids costly mistakes, but places total quality control over materials and assembly methods in the hands of Patriot Detection staff and management. Wire used in preformed loops is machine-turned and protected by high pressure/temperature conduit that is injected with a water-blocking material.

Patriot Detection preformed inductive loops are guaranteed to reduce or totally eliminate:
  • Numerous lane closures due to re-cutting conventional loops
  • Deterioration of the pavement due to re-cutting the pavement
  • Red light violations due to drive aggravation with “timed” intersection lights
  • Excessive exhaust pollution due to unnecessarily long red light waiting periods
  • Motorist call-ins
  • Timed traffic lights that require expensive equipment due to conventional loop failure


Patriot Detection P-ILDs offer the customer a significant cost savings. For both new construction and existing loop cut-in, Patriot Detection preformed inductive loops are a more cost-effective and superior alternative to standard electrical wire. Patriot Detection loops rated for direct hot asphalt pave-over and concrete overlay will compensate for reinforcing steel draw. Preformed loops manufactured for cut-in installations do not require “45-ing” the corners, or the use of a backer rod. Compared to other traffic detection technologies, Patriot Detection preformed inductive loops are in-ground and non-intrusive.
