The HISIC450 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 (e. g., induction loop signal). Even overheight vehicles traveling at speeds of up to 100 km/h are reliably detected. Due to its large beam diameter and high signal reserve, the detector can even cope with difficult weather conditions, i.e., rain, snow, and dust clouds.
