WebThe present invention relates to the technical field of ice detection, and provides an ice detector, comprising: an icing assembly comprising an icing rod having an ice accretion … WebDec 17, 2024 · This detector consists of a probe or a rod that is attached to a vibrator. The vibrator vibrates the probe at a fixed frequency. When ice builds up on the probe it becomes heavy, and thus the rate of vibration reduces. This reduction is sensed by the system, and once it falls below a predetermined value, an ice warning is given to the pilots.
