Abstract :
Describe the structure and working principle of piezoelectric resonant icing sensor, discuss the three measuring methods of the sensors´ resonant frequency, and analyze amplitude-frequency characteristics of the icing sensor. It proposes the groined icing alarm judging method for the actual needs of icing alarm system, and clarifies the steps of parametric determination and verification methods about the method. Finally, the validity of the method was verified by testing.
