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.
