Specs at a glance Measured variables: Overheight Measuring range: ≤ 100m for outdoor management Ambient temperature range: –25 °C ... +55 °C Degree of protection: IP67 ---------------------------------------- Field of application Endress Hauser's 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. • Overheight detection in front of tunnels and bridges • 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 Device properties:
