Asphalt road detector (vehicle detection sensor)

Sophisticated detector for smart traffic

The Asphalt Road detector is a specially designed strain detector that is adapted for installation in upper layers of the asphalt and under the roads so the detector flexes due to strain along any point of its length. This fiber optic detector uses the state of the art FBG technology with a unique mechanical design and superior sensitivity which enables it to recognize passing vehicles.

  • 100% passive detector 
  • balanced response with excellent sensitivity along its entire length
  • special design enables installation in asphalt infrastructure or under the roads
Request information

100% passive detector

Since the detector does not need the power supply, it easily monitors places without access to the power and hazardous or inaccessible areas.

Balanced response

The FBG detector provides excellent sensitivity along its entire length to ensure a balanced response to a whole traffic lane.

Special design

Special detector design with a minimal footprint enables direct and fast installation in asphalt infrastructure or under the roads. 

Protected as IP68 rated devices

The protection is comparable to the international standard rating of IP68 and guarantees complete dust tightness and protection against the effects of long periods of immersion in water.

Connectivity

The detector can be used alone or incorporated into a larger detection network to minimize the cabling costs.

Embedded monitoring

This optical detector is designed to be embedded into the asphalt structures in the upper layers of the road.

Immune to EMI/RFI

The detector enables operation even in harsh environments and hazardous areas. The advantage is immunity to electromagnetic/radio frequency interference.

Universal platform

The detector can also be used in combination with other detectors, such as the flooding or manhole detectors and other sensors, such as strain, temperature, pressure, etc.

Customized size

The detector’s sensitive length can be customized to match the road or lane width.
