Black ice detection

Sensice produces ice detectors that identifies the road surface state as being one of dry, wet or icy. It is further able to tell road surfaces covered by clear ice, often called black ice, from dry, wet or snowy roads and roads covered by sleet or clear ice with a layer of water on top of the ice. One of the most useful benefits is its ability to detect black ice, which often is near invisible to the human eye.

The detectors sense presence of ice over an extended area, typically extending a width corresponding to a road lane.

Applications

Sensice' instruments are often used for supervision of the road surface state. They may also be used for detection of ice on runways, bridges or wind power plant turbine wings. The instruments may also be used for meteorological purposes or in industrial applications.

Technology

Our ice detectors are based on infrared spectroscopy, which is the only viable technique. Sensice' spectroscopic instruments emit a beam of infrared light that hits an extended area. Light is partially absorbed by ice or water on that area, and light reflected back to the detector is sensed. Presence or absence of ice or water is then calculated using the optical properties of the retro reflected infrared light.

Advantages

Sensice' ice detectors use an innovative new design that allows a superior price/performance ratio. As compared to ordinary laser based systems the purchase cost is reduced.

Lasers have a limited life span, demanding regular replacement, which additionally gives competing instruments a higher maintenance cost. Sensice' ice detectors are not laser based, giving a significantly lower maintenance cost.
