摘要

Apparatus for detecting the presence of ice, and method for detecting the presence of ice on a superfu00eccie.It is a device for detecting the presence of ice which includes a sensor 101 including a transmission line of radio freqtiu00eancia 201, 202, providing a characteristic impedance, a source 103 connected to the transmission line 201, 202 and operable to inject a wave in the line of Ca Ansmissu00e3o 201, 202, a summation device 105, 106, 107) operable to create a wave static.The wave static, including the sum of wave and a reflected wave by the injected end of the transmission line 201, 202, the summation device 105, 106, 107 are connected between the source 103 and the transmission line 201, 202, and a detector 104 for detecting the voltage of the wave static.A configuration may include additionally a comparison device 112 operable to compare the voltage detected with reference data to determine the presence of ice in contact with the sensor.
