The invention belongs to the technical field of icing detection for aircrafts, and relates to a resistance type icing detector, which achieves the purpose of icing detection through the change of electrified current of an armored resistance heater in an icing environment, and is used for detecting the high-altitude icing environment where an aircraft is located and outputting an icing alarm and an icing grade signal. The icing detector is divided into an icing probe and a resolver. The icing probe is mounted outside an aircraft skin, is used for outputting current in different icing environments, and mainly comprises a probe shell, an armored resistance heater and a heater switching end, the resolver is installed in an aircraft skin, is used for monitoring the current of a heater, judging the icing condition and outputting an icing alarm signal and an icing grade, and mainly comprises an installation flange, a shell, an acquisition and resolving circuit board and a connector.

    本发明属于飞行器用结冰探测技术领域,涉及一种电阻型结冰探测器,在结冰环境下,通过铠装电阻加热器通电电流的变化达到结冰探测的目的,用于对飞行器所处高空结冰环境进行探测,输出结冰告警与结冰等级信号。所述结冰探测器分为结冰探头与解算器两部分。所述结冰探头安装于飞机蒙皮外部,用于输出不同结冰环境下的电流,主要包含探头外壳、铠装电阻加热器以及加热器转接端;所述解算器安装于飞机蒙皮内部,用于监控加热器电流,判断结冰情况并输出结冰告警信号以及结冰等级,主要包括安装法兰、壳体、采集解算电路板与接插件。
