Abstract:
1. A system for the measurement and prevention of icing in a conduit, comprising a plurality of sensors for acquiring mechanical oscillations of the conduit, an electronic evaluation unit and an electronic control unit, wherein the sensors are connected to the electronic evaluation unit, the evaluation unit comprises characteristics relating to the oscillation behaviour of the conduit and is equipped to compare the measured conduit oscillations with the characteristics, and by means of correlation to interpret them as conduit icing, and in the case of conduit icing to emit a signal to the control unit, wherein the evaluation unit is equipped, from sensor data and correlation with known characteristics that are associated with the conduit, to determine local and global increases in the mass of the conduit and thus of an ice layer, and, if a specified local or global thickness of the ice layer is exceeded, to emit a signal to the control unit for triggering a de-icing procedure.
