Ice Detection Sensor to measure icing and freezing rain for various fields of application. The IDS-20 system is setting the standard for the next generation of ice detection systems. The IDS-20 is the first non-contact ice detection system that is able to measure from 0,01mm up to 80mm of ice thickness. The IDS-20 system is an extremely flexible system to cope with different situations and applications. The system contains a central controller and three different sensors.

The sensors have different measurement ranges and applications. There are two cube sensors for icing measurement and icing detection for two different measurement ranges. Therefore, the IDS-Cube 1 sensor has a measurement range of 0,01mm to 1mm and is for the recognition of extremely fine ice layers and icing events. The design of the IDS-Cube 5 sensor is to recognize ice layers and icing events from 0,1 mm up to 5 mm. Additionally, there is a rod sensor that is designed to measure the total ice thickness throughout the season or year. The measuring range of the IDS-Rod sensor is from 1mm up to 80mm. The IDS-system design is made to be used with one sensor or up to max two IDS sensors at the same time.
