Description

The overheight detector monitors the height of vehicles – at tunnel entrances, low underpasses, or low bridges, for example. Reliable stop and alarm signals are activated when a vehicle infringes both photoelectric switches of the HISIC450 and this signal is then combined with traffic data. Even overheight vehicles traveling at speeds of up to 100 km/h are reliably detected. The detector can even cope with difficult weather conditions, i.e., rain, snow, and dust clouds.

Field of application
  • Overheight detection in front of tunnels and bridges


Device properties:

  • Aluminum enclosure with anti-corrosion coating and high enclosure rating
  • Built-in lens heaters to prevent condensation or icing
  • Weather protection against snow, rain and dust clouds
  • Accessories (weather hood and mounting bracket) made of stainless steel
  • Sensitivity adjustment
  • Insensitive to ambient light
Benefits
  • Reliable alarm signals – even in nasty weather conditions
  • Reliable detection of overheight vehicles traveling at speeds of up to 100 km/h
