Detection ranges

The detection range of the ice detector is intermediate, but other ranges may become available at request. With increasing detection range the cost of the system increases, so choosing a detection range suitable for the application is important. The cost increases step-wise as a choice has to be made to use more sensitive detectors or more powerful light sources. Given a chosen detector type and light source type, actual detection range may be varied slightly, typically by a factor of 50% up or down, by changing aperture sizes.

Intermediate detection range

For medium range detection, applicable to i. a. detection of road surfaces in front of a vehicle, amaximum detection range of 50m is typically more useful. With an advance warning of upcoming icy patches on the road 50m in front of the vehicle, this gives a driver running at 90km/h (65mi/h) 2 seconds to respond and slow down.

Short detection range

For short range detection, applicable to i. a. ice detection at entrances to buildings, walkways or similar, a maximum detection range of 5m may be useful.

Long detection range

For long range detection, applicable to i. a. ice detection at airport runways, where the safety distance to any object has to exceed 75m, a maximum detection range of 100m or more is often necessary.
