Asphalt Detector - Road Detector

Asphalt detector

Sensitive detector for smart traffic 

The Asphalt Road detector (FBGS-01 AR) is a specially designed strain sensor which is adapted for installation in upper layers of the asphalt and under the roads. The condition is that the detector can flex due to strain along any point of its length.

This detector uses the state of the art FBG technology with unique mechanical design and superior sensitivity which enables it to recognize passing vehicles. 

  • 100% passive detector 
  • Balanced response (excellent sensitivity along its entire length)
  • Special design (enables installation in asphalt infrastructure or under the roads)

Features & Benefits

  • Universal platform for use with other types of detector    
  • Monitoring
    designed to be embedded into the asphalt structures
  • Customized size according to the width of the road or lane

Protected as IP68 rated device

Complete dust-tightness and protection against the effects of long periods of immersion in water.

Immune to EMI/RFI

The technology is fully passive, explosion safe and immune to electro-magnetic/radio frequency interference.


The detector can be used as a standalone sensor or in series as part of a larger detection network to minimize the cabling costs.
