The ice detection sensor IDS-20, in the shape of a cube or of rods, is used for the reliable and precise measurement of icing in aviation, for wind power plants, high voltage power lines, cable cars, antennas, overhead wires, streets, buildings and constructions and wherever the formation of ice constitutes a potential risk.
Measuring principle
The innovative ice sensor makes use of the different physical characteristics of air, water and ice at varying frequencies. Measuring the complex impedances within the medium around the sensor the IDS-20 is able to distinguish between water and ice and hence recognise the formation of ice.
Increased data quality due to plausibility check
The formation and accretion of ice depends on specific climatic conditions determined by the state of the air temperature, hymidity and the temperature of the surface, where the ice adheres to.
Now, the unique and very valueable feature of the IDS-20 is that it additionally considers meteorological data for the purpose of a plausibility check:
Parallel to the ice sensor the system measures the air temperature and humidity and thereof calculates the dew point and frost point. The sensor system then uses these data for a plausibility check together with the ice values measured. Therefore, it is possible to qualitatively increase the reliabilty of the measurements and improve the ice detection results.
