Plausibility check

Formation and accretion of ice on a surface depends on specific environmental conditions determined by air temperature, humidity and surface temperature.

The IDS-20d uses the present meteorological conditions to verify the icing measured by the ice-sensors: Parallel to the ice detection the IDS-20d measures the air temperature and humidity and calculates the dew and frost points. With these data the IDS-20d checks if the conditions actually permit the formation of ice as detected by the ice-sensors. Thus, icing events are detected with high reliability.
