break beam sensors

Break Beam Sensor

Infrared sensors are mounted on either side of the road in advance of the low structure, transmitting infrared beams over the road.

When an overheight vehicle load breaks the infrared beams, it immediately activates the system’s warning devices.

An independent study by the Joint Transportation Research Program found that these beam sensors offer superior reliability and environmental robustness at a reasonable cost.

The result is advanced warning to only the vehicles that present a danger to infrastructure.
