DEVICE AND METHOD FOR MEASURING ICE THICKNESS

摘要

The present invention relates to a device (100) and method for measuring ice thickness on a first surface (110) of a construction element (120). The device comprises a sensor arrangement (130) arranged in connection with said construction element and arranged to provide signals related to an impedance, and a processing unit (140) coupled to the sensor arrangement (130) and arranged to determine the presence of ice based on the provided impedance signals. The device comprises further a reference sensor arrangement (150) arranged to generate reference impedance measurement signals. The processing unit (140) is further arranged to determine the ice thickness based on determinations of a relation between the impedance signals determined by the sensor arrangement and the reference impedance values generated by the reference sensor arrangement.
